It told me "Pixel format not accelerated". Yikes, what can i do?
I just formatted my computer and no longer have XP or any other OS than 7 :S
EDIT
Not to mention I chose all the complications making a MMO RPG in Java means so everyone could use the game, including Windows 7
EDIT 2
It's a 64 bits Windows 7 Ultimate but I also got this same error in 32 bits Windows 7 RC, I think it used to work in the Beta, but I can't remember well.
EDIT 3
I'm using the drivers that Windows 7 came with, didn't install any other drivers. Aero is working fine so I guess my graphics card is working properly. Last time I installed the GeForce drivers, when I had W7RC, graphics just stopped working (Both Aero and games), so I had to go back to the ones Windows comes with. =/
