Do you have any other computers in the house that run anything besides Vista?
Have you tried taking your computer to a friends house to see if maybe it is your internet connection?
The problem with that is....most accounts have multiple servers streaming.....and a few have 50+....would be easier to just edit the text as you did :)
You need to submit a ticket to EvenBalance and explain your problem in depth.

Also, spamming the other areas of the forums won't get you answer faster :)
