To the posters who have an Intel graphics card issue : OPENGL failed to start.
I am running same type(IntelĀ® 82915G 128MB)
Windows Vista
2gig ram
I went to the Intel website, looked up the driver name. Only had XP/2000 driver so, did a restore point ( ) and loaded the XP driver on my Vista PC.
Rebooted and CM:SF demo works!
