I'm somewhat relieved to see I'm not the only one. I am getting the exact same error:

I am however concerned that this thread has been running for almost a month.
I've only had this problem for an hour.
Do I need to do anything for FiOS to fix it?
Luckily I happen to have a Cablevision ID as well; I am watching my Sopranos with my Cable login for the time being.
It's extremely disturbing that I'm paying Verizon over $200 a month yet I personally pay Cable nothing, yet my cable login works and Verizon's doesn't.
