[I crashed and can't log in now because it said i can't access from this computer. Please help.]

I was just in sl.  I have done nothing wrong.  I buy all my stuff.  I don't go anywhere i shouldn't.  Don't do anything against TOS.  But now i find myself locked out with Can't access sl from this computer.  I have uninstalled my viewer and retried it and still getting the same thing.  I know it is not my router problem because my husband can access his account.  We go by the rules but the TOS so what is up please help.  I am a designer and sim owner i need to get on.
