Sure you are putting in the correct username/password?
if so, then it could be that either someone/something has changed your password or AOL has blocked you from logging in because of a suspected malware issue.
just use the help pages on AOL, try to contact them. set up a new email to do this from and they should help you solve the issue. I think they might ask you to prove its your account, so you may need some information regarding old emails etc.
