Me neither. I think it's only the fact that I woke up early to play the game :cheers:
My cell alarm was at 2h50 AM (3h00 AM is the HL2 release) and it didn't work. I woke up by myself at 5h00 AM :afro:
Guys that have problems with their PC should check their PC first.
I got a pretty basic system (P4 2.4, Radeon 9800 Pro with 1GB of RAM) with XP SP2 and it works fine. Didn't formatted for 1 year.
Bought with Steam...works great.
