What you are experiencing seems to be a reacurring theme for many. There are a bunch and a half of things you can try. I tried most of them (3+ hrs) and ended up calling tech support. After a half an hour of the phone with them it was up and working and I haven't had any problems since. Just givre them a call. That's my advice. They have a whole list of steps they talk you through in order. It's just not worth all the tinkering.
