Hello, I just installed the trial of mudbox and wanted to compare it to zbrush however when i launch it it seems to load fine, i try to import and obj and the viewport does nothing just a big gray box. I then tried just making a basic mesh and i cant even see my cursor in the viewport area just a big gray area that appears to do nothing. I am running 3ds max 2008 fine, its basically a brand new computer, im running windows vista 64bit with an asus Geforce 8800gt 512mb video card direct x10. Any help would be appreciated as i only have 30 days to try and get it to work to make a purchasing decision.
