.Net Passport problem with Windows XP, SP2

​ Hi everyone. I'm having a problem with signing on with my Microsoft .Net Passport. I have a Dell Dimension 4700 and run IE7 Beta 2 (the new one) on a cable connection, I have my Passport associated with my user account on my Windows XP, SP2 and I have the following installed - Frame .Net 1.1, 1.1 Hotfix and the newest Frame .Net (2.0 I think) on my home computer (I'm at work now). I cleaned my computer last night and the only thing I can think of is that I DID delete a User Account called ".ASP something or other". Could that have messed things up. Woud I have to re-install all my Frame .Nets (I already Repaired 2.0 last night). Please help me with this I believe, .Net Passport may be messed up and I have to fix it. Thanks in advance, and please be as detailed as possible (I'm a novice!) Thanks! ​
