i have a problem where i can play R1GL online but when i try to put my 3d card into the game it says it is having trouble resizing window and wants me to debug it to work

, i know its not the 3d card because when i go to the Quake 2 demo my 3d card works so i dont understand what the problem is im hoping someone on here can tell me, if you know how to fix this problem so i dont have to use software please contact me on
