Today I migrated from MultiBit Classic to MultiBit HD 0.4.1. I received my 2BTC, so I thought everything was fine ... untill ... I restarted MultiBit HD.
After login in with my password i get "The password did not unlock the wallet".
- I checked the password with "I have forgotten my password" option and my password is 100% correct.
- I also tried to recover my wallet from the last backup with the wallet words. The wallet words are verified but after what seems to be a successful recovery, I get the same message "The password did not unlock the wallet".
- I also tried to recover my wallet from older backups, but this did not work either.
- I tried to download lighthouse, which should be compatible with MultiBit wallets and wallet words, but the site is down.
- I tried to recover my wallet on a 32-bit laptop, using a 32 bit version of Multibit HD (which was difficult to find BTW) but I get the same error: "The password did not unlock the wallet".
Note that my backup folder is on an encrypted TrueCrypt disk. The original wallet is just on my C:\\ drive. I keep the backups on a TrueCrypt disk to keep my files in one place and for easy backup purposes. I never had problems with encrypted disks though. They work just like any other disk. It worked with MultiBit Classic too.
I'm kind of panicking now. It's a lot of money locked in

This issue is described in some older threads, but apparently it is not solved?
