• Software Development for Windows Vista Which Ati Drivers for my X800PRO?.I have 5308

  I dont want to screw up my computer cause when i tryed to install the xp 64 drivers, i got errors about running in admisistrator mode(which i was in).

I'm using build 5308 as well, and i'm having trouble with the ati 5270 catalyst drivers as well. my card is an ati radeon x800 xt pe.
