I need to decrypt the trillian aim password on my computer. I have forgot the password.

I have searched google, from google i have found Advanced Instant Messengers Password Recovery, it has a free trail but will only decrypt
up to a 3 character password, mine is longer...

I have also searched antionline.com I did find a post from sonic about decrypting the trillion password witch does not work on the AIM password.

I have ran out of idea of what to try any suggestions would be helpful and appreciated.
