When I was trying different passwords, I was getting "Provided AES key is wrong" only for a specific one. No other password was giving me this same error message. I then concluded that this was the wallet password, that Multibit was working wrong and that some corruption occured.

I was wrong. gunrnec's tool helped me trying more passwords combinations to finally find the actual one, unlocking the wallet.

That's why I say that "Provided AES key is wrong" error message is not related to what I thtought was the actual wallet password. I don't know where it is coming from.

Like many others, I thougth I was remembering my password and blamed Multibit when in fact, I was not vigilant enough to write it on paper at the time.

I hope it is clear now... Good Luck !
