So that settles it. I need another Gig, or at least another 512 MBs worth. Planetside takes up about 300 mbs of memory before it crashes. The only way it doesn't is if the planet I was on is now in enemy control and I get transported back to the sanctuary. There is less to load when you're in a sanctuary, so it takes less memory. That's the problem I have. The game runs fine when I load everything up right, but the loading process crashes it.
EDIT: Oh and by the way...
