I've been getting this error the past few days or so. "No OpenGL compatible graphics adapter found. This is either caused by a missing or outdated graphics driver" It instructs me to install the latest driver for my vid card, etc.
The problem is that I get this error after I've already played the game successfully. lol...The first time this error showed up I'd literally just logged off the multiplayer server I was on (it was restarting) and quit out of the game. Once I tried to go back into the game (about 3 minutes later) I got the above error.
Just now I got it again. I played last night, no issues. The computer has sat idle all day while I was at work, now I try the game again and get this error.
Last time it happened, rebooting my computer fixed it. I'll try rebooting again after I post this, but having to reboot every time is going to get old fast (I get no errors dealing with my vid card on any other game, and I know my drivers are up to date as I just updated them two days ago for another game)
