Aim account hacked

I can only assume my account as hacked, as my password is no longer working and when I try to use the recovery function, my secret question has changed as well. Apparently the e-mail associated with the account is still mine, however, so is there any way...

I can get it back?

you can either get a new screen name or change your password, if the hackers didnt do that already

From the AIM web page, itself:

Q: Are there any known security issues which might affect AIM?

A: A security hole in the Windows version of Internet Explorer allows a malicious web site to run dangerous code on your computer if you visit that web site. The attacker can then control your computer, and sign on with your AIM Screen Name if your password is stored (although your password would not actually be revealed). If you think your computer has been compromised, you should immediately change all of your AIM passwords here. All users should immediately install the security patch, available from Microsoft at http://www.microsoft.com/technet/security

This may not be what you are experiencing directly, but the link should be helpful for you to contact them and explain the situation.
