I recently bought Half-Life 2 and had trouble trying to install. My PC was unable to read the Disk while trying to install. So I took the game back and got a new CD... and upon trying to install on my PC again the disk couldn't be read. I thought perhaps it was my PC but my PC recognizes all my other gaming CD's. Plus my wife's PC wouldn't read the disk. Should I just give up on Half-Life 2 or try returning for a 3rd time? What would you do? I'd like to play this game, but it's really becoming a lot of trouble. Thanks all.
