The game used to work on Ubuntu, but after I repaired windows XP and deleted Ubuntu it wouldn't work.
After picking Level Editor or starting a level/map pack the game crashes. My specs:
Packard Bell Computer
Intel(R)
Pentium(R) 4 CPU 3.06GHz
3.06GHz, 512MB of RAM
Nvidia GeForce FX 5200LE
Mari0 won't work on Windows XP?
Make sure the OS is up to date and install the latest drivers for your GPU (http://www.geforce.com/drivers/results/5753)
