Thanks for the tip jim618,

I like the consent of having all keys generated deterministically from the "wallet words". I will definitely check it out!

One thing that i did not mention when i created this thread is that i have replaced the harddrive on my laptop. I still have the old hard drive and when i started dig in to my old ubuntu installation in the old disc, I found that Multibit generate a log file. So i opened the log file and searched for my lost BTC address and to my surprise it was there!
the log also contained the location of that wallet that was used to generate it, and it turned out that i had been using a wallet that was basically an old backup of my normal wallet. the Old backup was still there on the disc so now i have my BTC back:)

sorry for wasting your time with such a trivial mistake;-)

I have the wallet_name-data folder and wallet_name.info file and the wallet_name.wallet file.

but if i understand jim618's answer, that don't help if they are the wrong version.

thanks for the answer anyway.

Hi jim 618,
I was hoping that the keys, to some extent, was generated deterministically

Thanks for the informative answer, now I at least know what to focus on.

I will go thru my old hard drives and see if i can find any backups with the right key.

Somehow one address that I used to receive 7.68 BTC from bitstamp.net is gone from my Multibit wallet.

I have been using Multibit 0.5.18 on an Ubuntu laptop, the wallet was placed inside a Truecrypt vault that was placed in a Dropbox folder. I have also been using the same Dropbox account on other computers and I assume that the Truecrypt vault was synchronized in such a way that the newly created address in the wallet got lost.
I have now been generating hundred of new addresses in my wallet in hope of by magic finding my lost BTC, but so far no luck.

Is my BTC gone forever or can the private key for my address be generated given that I have the wallet and the password?


the BTC address is:  1B5CNWL6SmCMT9AawaGo1kBDrHG5Cbi2zD
