Particles aren't working right on my comp!!!

here are my specs:
AMD K6-2 450Mhz
voodoo 3 2000

those should be all the specs you need.... tell me if you need other.. here's the problem.

screenshots on how the particles i made work on my friends computer (we both were on the same server, mine):




and these are mine:



i reduced mine cause they're huge in bmp but you get hte point.. anyone have any idea? (BTW T2 particles worked fine for me in T2 but v12 particles won't);
