Unfortunately the only .wallet file that I really need to open gives me the same error that I have been getting. There is no .info or .key file associated with it. I suppose whatever went wrong last week didn't allow for those to be saved. I'm not sure what else to do.

EDIT: oh, hold on, it seems to be opening another .WALLET file (I don't think my BTC will be in this one), but it's working for a file from the day prior for some reason. I have to wait for it to sync up, and I'll let you know how it goes. (not sure why it won't open the file I actually want to open)

-------------------------

I just moved the multibit.properties notepad file into the downloaded "Multibit Classic" folder and ran multibitclassic.exe. It worked and filled in the file, finally giving me a welcome screen when I ran the program.

I have .WALLET, .INFO, and .KEY files for each backup. (other than the most recent one from a week ago, for some strange reason, there is just the .WALLET file)
-They were all contained in a multibit-data folder in Users/[user]/appdata/roaming/multibit

I just tried moving the entire multibit-data folder, a copy of the .WALLET file, and a copy of the corresponding .INFO file into the downloaded "Multibit Classic" folder as well, but again, after trying to OPEN WALLET, it gave me the same error.

I had to enter a password to use my wallet if that is what you mean. (Forgive me, I'm not sure if that means it was actually encrypted or not.)

I did not take the steps to find the private key because it sounds like something is going wrong before that step.

Thank again.

*Be sure to post or message me your BTC address so that if I figure this out, I can send you a few bucks for helping me out. I don't have much, but I really appreciate it.*

I believe I followed the instructions step-by-step, but I still get the same error when trying to open the wallet.

Just to be clear, the multibit.properties empty text document should just be sitting in my MultibitClassicPortable0519 folder in my C Drive?
I don't actually know what this does because I know very little about computers, in general, so I just want to make sure.

Thanks again.

Thank you so much for instructions even a newbie should be able to follow. I'll try it out tomorrow.

Cheers.

On an old version, 0.5.18 on Windows 64 and I am trying to load a wallet with a .wallet file from about a week ago in the rolling backups folder, but I keep getting an error, "Could not load the wallet file.......Error message was "null."" Do I need to put the file in a specific location or do I need to update my client first? I have made copies of all of my wallet files.

I'm not sure what other information would be useful to you, but let me know what else you might need to know and I'll provide it. I'm very new to this and obviously it's been a while since I messed around with it since I am on such an old client version. I'll be updating as soon as I get this all figured out.

Thank you in advance.
