UPDATE: I just up-voted a couple times. Seems to be working for me now.
I have tried upvoting a couple times since the new price. Does not seem to work for me. Error message disappears before I can copy it. Something about 'can't find a big enough something'.
I have something called PeerBlock going and an IP address said to be the "Halliburton Company" is trying to access my computer a lot. It tries all day every day. I hate to whitelist something with such an evil reputation since I am under investigation already. Not sure if that's a related issue.
