Hm, that seems to be the problem. At least with the Radeon card, after updating it's driver SU doesn't crash and textures are displayed normally. Thanks for the advice!

Anyone else experiencing this: it started with SU 7 and got worse with 7.1. Every time I open a model that has textures, SU crashes. It happened on two computers, both running WinXP SP2, one has a Radeon4830 card, the other has an on-board Intel thing. Now I can't use ANY textures/materials at all. I tried different graphics settings, uninstall then reinstall SU but that didn't help. Any suggestions? Should I revert back to SU 6 or what?
