No, you should open it from inside the MultiBit program... then use "File -> Open Wallet". Don't try and open it in wordpad or notepad etc.

Also, you have opened the multibit.info file... you want to open the multibit.wallet file (or the multibit-[YYYYMMDDHHMMSS].wallet file from your wallet-backup folder). The YYYYMMDDHHMMSS is the Year-Month-Day-Hours-Mins-Seconds that the file was created.

Pick the one that has the date before all your coins went away.

You can also check those "receive" addresses on www.blockchain.info (or another block explorer) to make sure they still have coins in them.

  Thank you again for all your help!!

  BUT how do I Open it from INSIDE the Multibit program?

  Thank you for that blockchain.  Link!!!  the addresses in the file ARE My Bitcions.  Now if I can get them back in a wallet safely without loosing them again.

 ok now that I searched the address,  can some one steal my coin from that website with my coin address on that site?

No, no one can steal your coins just because you checked the address on blockchain.info

And regarding opening the wallet from inside Multibit:
- Open Multibit
- Go to " File --> Open Wallet"




- It will ask you to browse for the .wallet file
- Navigate to the desired folder and choose the .wallet file you want to open

  I tried what you showed me for more than an hour,  every way I could think of but it still will not open in the wallet.  I have it open on a notepad file.  but I can't get it in a wallet.

So you have opened MultiBit...

And you selected: "File" -> "Open Wallet"

It should have opened a window asking you to select a wallet file, did you see something like this:


You want to select "multibit-data", then click "Open", you should see this:


Now you want to select the "wallet-backup" folder and then click "Open", you should see the "multibit-YYYYMMDDHHMMSS.wallet" files:


Select the wallet file you want and click "Open".

You should go back to the main multibit window, and it will start synchronising the wallet. This may take a while, so be patient. Smiley After this has finished you should see all your addresses, transactions and coins.

 is there a way to put the addresses in manually.  one at a time.

 adding the file has not worked.  I tried many  times.

I beginning to wonder if you have been hit with the MultiBit wallet corruption issues that a couple of other users have had... Undecided

Either that, or you've been hacked and don't actually have any bitcoins left... have you actually checked your addresses on a block explorer like blockchain.info to see if they still contain coins?

Also, check your PMs...

  It was a power shut down when the wallet was open.

  Yes I checked one address and it showed .1 bitcoin,  so I still have my coins. I just cant load them in the bitcoin wallet.

Did your multibit wallet have a password? If it's corrupted but didn't have a password then retrieving the coins will probably be easier than if it has a password.

  No password.  I live alone and no one around here knows what BitCoin is.  I didn't want to get locked out of it also.

I can't promise anything, but if your multibit wallet file is only a little corrupted you might be able to use the quoted instructions to get your coins back. Basically they explain how to open your multibit wallet file in something called a hex editor and use it to search for 08011220. If you find that number then the next 64 characters (32 bytes) could be a private key for your wallet.

You can change that private key to a format the electrum wallet accepts, and import it into electrum to get your coins back.





Since version 0.4.0 multibit classic wallet files are in a format called Google protocol buffer format (protobuf). Open a file with a .wallet extension in a hex editor and look for the following sequence of bytes 08 01 12 20. The next 32 bytes after that should be your private key in hex format. After you get your private key in hex format you can convert it to a normal format using an offline copy of the bitaddress website.

I tested this on an unencrypted wallet (one with no password) in multibit version 0.5.1.6 and it worked for me.

This is the hex editor I used, although any other is probably sufficient.

https://sourceforge.net/projects/wxhexeditor/

This is the bitaddress website. I advise you not to directly paste private keys into it.

https://www.bitaddress.org/

Instead look for this link at the bottom of the page and use it to download a zipped copy you can run offline.

https://github.com/pointbiz/bitaddress.org/archive/v3.3.0.zip



This is my multibit wallet file opened in the hex editor with the bytes 08 01 12 20 that precede a private key highlighted.






This is the 32 bytes of a private key (in hex format) highlighted.







This is the 32 bytes of a private key (in hex format) copied directly from the hex editor into notepad.






This is the 32 bytes of a private key after removing the spaces in notepad.






This is the private key copied from notepad and pasted into an offline copy of the bitaddress wedsite. Click the view details button to get the private key converted to normal formats.





This is my multibit wallet's address 1F84fkbMng6dJpGZmtycRbUe72B7XSYbeT shown on the right hand side of bitaddress. Every raw private key can convert into two different bitcoin addresses, which is why there's two.






This is my multibit wallet's address 1F84fkbMng6dJpGZmtycRbUe72B7XSYbeT shown in multibit.




You can import your private key into the wallet of your choice to get control of yours coins back. Electrum's a good choice.

The most frustrating part about all this is that it would probably take less than 5 minutes to recover all of the coins... no password on a MultiBit Classic wallet means that with a simple python script, all the private keys can be dumped directly from one of the wallet files in the "wallet-unenc-backup" directory Undecided

However, I get the feeling that installing Python and using a command line based Python script is going to be way beyond the technical ability of the OP, given their obvious struggle with some computing basics like working Explorer and copy/paste.  Undecided

So, I have been experimenting with "pyinstaller" and "Tkinter" to create a standalone Python version of my script that extracts pubkeys and privkeys from MultiBit Classic .wallet files. I have even created a GUI for the script, so the user doesn't need to know or use the commandline... you just extract all the files from the .zip and run the .exe from Windows Explorer:



Then you use the dialog to select your wallet file (maybe copy your .wallet to the same directory as the script first):



Enter a password if the wallet has one (if you don't have a password, you won't be prompted):



If there was a password, you'll probably have to wait a little bit for the decryption process to complete:



Then it should dump out the Addresses and matching PrivKeys (it even autodetects if using compressed or uncompressed keys and outputs the appropriate PrivKey):



Credits: Christopher Gurnee (gurnec) and his BitcoinJ Seed Extractor... It should be fairly obvious that I've borrowed quite heavily from his script Wink

The source code for the script (which can also be run from the commandline if required) is here: https://github.com/HardCorePawn/extract_mbc_keys
The zip package is here: https://github.com/HardCorePawn/extract_mbc_keys/raw/master/extract_mbc_keys.zip

NOTES:
  • Yes, I know distributing .exe's is not best practice... but if you read this thread from the start, you'll understand why I have chosen this solution. Undecided
  • The source script is included in the github repository, so it can be peer reviewed and/or you can "compile" it yourself using pyinstaller.
  • This package will ONLY work on Windows... it's just the way pyinstaller works... it was "compiled" on Windows, so it runs on Windows. If you want to compile it for Linux and/or MacOSX feel free... the source is there and pyinstaller apparently runs on Linux/MacOSX.

I hope OP isn't messing around with us. Every time we ask for some information, he comes up with something really absurd.

Now I think I was right. OP was just messing around. No response from him after we went through all this trouble of teaching him simple tasks like copy/pasting and even opening a file.

  I have been on tractor brush hogging and mowing almost every day. it has been wet spring that makes a lot of weeds and grass to take care off.  That is how I make the money for the bitcoins.
 
did any of you hear what Mcafee said about bitcoin?  saying it could go to .5 mil in 3 years? http://www.gcnlive.com/JW1D/index.php/archivespage?showCode=1

If so, did it manage to extract any addresses/keys from your wallet? If not, did you get any errors? Huh
