Also if you can, please try to recreate this crash in Topaz Photo AI, then go to Help > Open Log Folder, please send me all of the files within that folder. You should be able to attach them directly as a response to this thread.

Hi John. I was helped by one of your tech support people. The ultimate fix for my issue was to change the AI Processor under the general preferences to manually select my video card, rather than allowing it to auto select. When manually selecting cpu, the system would also lock up. Thanks!
