Kal, you don\'t seem to have much memory to run both Win2k and Planeshift. Sometimes, you may be able to run it but experience swapping (the game may easily use as much as 300MB of main memory, if your computer doesn\'t have as much, it will use the harddisk a lot), and sometimes it may just crash because your virtual memory is too small : 291 MB is not enough.
Try to increase your physical memory, DDR266 is not very expensive, though if you intend to upgrade soon it\'s probably not worth it. Also, find some space on your harddisk to increase your virtual memory as well. If you know how to do, I would even recommend setting a constant size for the virtual memory (same value for initial and maximum size parameters), to avoid disk fragmentation.
