Hello Civ Fanatics. First time poster here. I've played Civ. 4 on my Windows 7 computer many, many times, most recently last weekend. But now it's just stopped working, and I can't figure out why. I clicked on the game and nothing happened. I opened "Process Explorer" to see if it was trying to load, and it did indeed appear there, as "Civilization4.exe" with "Rundll32.exe" immediately underneath, but they weren't doing anything. I killed the process and tried clicking on the game again. The two files reappeared on Process Explorer, and there was a brief burst of CPU activity, but then they went down to nothing and nothing happened again, even though they stayed on the list. If not for checking Process Explorer, I would not even know that the game was trying to launch, for nothing at all appeared on screen, not even that little box that shows the progress of loading. I tried restarting the computer. It didn't help. I tried uninstalling and reinstalling the game. It didn't help, either. I tried reinstalling the DirectX from the C.D. It didn't help. In desperation, I even tried turning the computer back to a Windows Restore point generated about a week ago. The system hadn't done any Windows Updates in that time, but I figured what the hell, it can't hurt, right? But it didn't help. I am out of ideas. I can't figure out why it would work last week but not today. Does anyone have any suggestions? In the meantime, I am going to go play Civ. 4 in the basement on an old XP computer that still runs the game (slowly).
