Just some basic reasoning, here...so far, at least two of the complaints I have heard are from people who (like myself) ordered Overture from gamersgate.com
today. I was looking through the forums earlier, and did not happen to see any threads about connection issues, aside from this thread.
So, either a) if there are other threads that I might have missed, the problem has been going on for a while, or (what I think is more likely) b) they are experiencing server downtime, or otherwise just a hiccup in the system.
Of course, I most definitely hope that it is the latter, as I really look foward to playing this game soon.
H4nky, did you order Overture within the past 12 hours or so?
