Spring RTS Engine

Since I installed a new graphics card I have only been able to use around 10% of my maps yet when I remove it I can use all the maps. Its a e-Geforce 6200 (nvidia) AGP8x 256mb ddr2. The few maps I can play are decent but I really miss some of the older maps I played.

P.S. If this is in the wrong area I'm sorry.
