Any luck? or ideas? 

Thank you for your reply 

The password for one of the wallets contains a '. This password is extremely long, almost 40 characters, but its basically words, no random lettters, so more difficult to get wrong.

The password for other two wallets only contains letters and numbers.

So three wallets, all passwords wrong, seems unlikely to me, and more likely that there was something wrong with the encoding of the backup key file? But like you mentioned, it doesnt seem corrupt, since its not giving any weird messages using your script, just the incorrect password message. I've tried all three scripts for the .key .wallet and .cipher file, all the same problem.

I can't see any reason why the computer would of been in a language other than English, but i was in China for that period whilst I was using the wallet. I don't speak chinese and the computer was not bought from China, it was a Macbook.

I have the exact same problem. Three seperate wallets, three seperate passwords, all giving the "password is incorrect"" when running your script on the .wallet .key and .cipher files. It CANNOT be that all three passwords are incorrect, they are independantly written down and just not working.

I know these passwords have worked before in 2014 because I used them to make payments. I actually gave up back then, but I''m now picking this up again, with the hope of recovering the coins.

My only other thought, maybe the multibit classic wallet corrupted the password??

Finally, maybe in an upside, I still have a running version of the Multibit Classic wallet on an old cloned drive, could this help? I can see the wallets, and the balances, just can't export the keys or send any bitcoin, because it is saying password incorrect.

Would greatly appreciate this help!
