Did you install the latest update from the AMD site?
What OS version are you using?
What does the crash report say?
I went to AMD site and installed the latest Catalyst (12.8), but did not see my card model listed in the .inf files. Using Win 7/64. No crash report - program just freezes. Ex. when I try to merge 3D layers after creating 3D postcard out of 2 layers.
Really basic question... Did you reboot after installing Catalyst 12.8?
I haven't tried 12.8 yet. On my list of things to do...
OK, freezes and crashes are very different things.
(and your title originally said that the machine crashed: which is an entirely different matter)
We'll have to see if the 3D engineers have any more ideas.
