Ok so i downloaded various stealing scripts to have a bit of fun with my friends, I later then deleted them. everything was running fine till i then later tired to sign in and i got the following:
I had a message telling me that windows live had encountered a problem and needs to close. I then sent the report  but the problem still presists. I even uninstalled WLM and Messennger plus twice, and the problem still presists.
The main problem i know get is that anytime i sign in, i still have the display picture of the last person whos identity i stole and they are the only ones who can see it. Everyone else just sees that blue messenger man thing. Even when i change my dp it has no effect. So does anyone know what is wrong and what i can do to fix the problem Thanks.
I am using the following system:
Windows XP.

1. Quot Messenger completely.
2. Go to C:\Documents and Settings\<username>\AppData\Microsoft\MSN Messenger\<non-zero number>\UserTile and delete all the files there.
3. Start Messenger again.

Note: For Vista, the path is C:\Users\<username>\AppData\Roaming\Microsoft\MSN Messenger\<nonzero number>\UserTile
