Hi,
I had the same version 13.9 problem (FSX crash). It was resolved bij copying atiumdag.dll into the FSX main folder. But I found that there is a newer version. I installed that Catalyst version 13.10 beta and everything works fine now, even without copying that atiumdag.dll file...
regards,
Erwin
