Exceeding hourly rate- when the pc was off.

My PC's been disconnected for the past 12 hours. Turning it on this AM I'm getting exceeded hourly rate warnings, in both Twhirl and Twitterfox.

I see this usually after I use Twitter Karma. However, I've not done anything at all for over 12 hours. And Twhirl, and Twitterfox were both off- not in the task, but really off. I understand TCP-IP and they weren't communicating.
 
sad I’m frustrated
