Gamers who tried to play Gears of War on the PC Thursday ran into a slight snag: it seems that the digital certificate that allows the game to run expired on January 28, 2009. Basically that means if you keep your PC's clock up to date, you can no longer play the game. The official Epic forum is ablaze with complaints about this issue, as the still-kicking community becomes enraged.

"I had this problem this evening, I had to change the date and time (from PM to AM) and I am able to get in just fine," one frustrated gamer posted. "I also changed it back to the current date and time and it didn't work. Change it back to yesterday AM and it works fine... EPIC games won't be on my list anytime soon...."

Epic Games is aware of the issue, but don't expect much hard news about what to do about the inability to play the game. "We have been notified of the issue and are working with Microsoft to get it resolved," a super moderator posted on the forum. "Sorry for any problems related to this. I'll post more once we have a resolution." (Microsoft is the publisher, and GoW is a Games for Windows release.)

Until then? You can either fiddle with your computer's clock or not play. Neither choice is much fun.

While it's not rare for games to ship with bugs every now and again, it's pretty shocking when one ships with an issue that causes the title to stop working.

Update Mark Rein has released a statement clarifying that GoW's anti-cheat technology is to blame for this issue, and not the game's DRM."
