I'm logged out of my account automatically as soon as I log in, after dl NAV 2010

Hi everyone - I downloaded NAV and it eliminated a problem I was having just fine.  But now as soon as I try to log into my account (or any account on my windows), it logs me in, then immediately logs me out.  I can't even connect to the internet, or do anything offline because of this.

 

Any ideas?  TIA!
