Hey guys,
Ive got one problem using WLM.
When i try and change my nickname, it doesnt get updated. It shows on the main dashboard as updated, but it doesnt update in the contact list(since i added myself on msn). And then, if i sign out(after trying to update my nickname), the next time i sign in, it shows the 8004005 error ALWAYS. Now, i know that if i delete the windows live contacts folder that the error goes away, but the problem is that i cant change my nickname, wihtout the error coming up next time i sign in. The only way i can change my nick is to sign into windows messenger, change it there, and then go back to wlm.

Any Solutions?
