I'm running an AMD Athlon with xp 2000+ (with Windows xp pro sp1) 1.67 Ghz processor, 1 Gb of RAM. I'v utilized only 19% of my recources, yet I'm unable to render down (even dynamic ram previews) at a high resolution. SF tech support has had me delete, uninstall, re-install, yada yada yada. I currently can't even get 20 seconds into a 30 second project when rendering or building a preview. any Ideas?
