I've downloaded MSI Afterburner, enabled the statistics server (overlay). Started the game, made sure the MSI Afterburner overlay is visible and then I activated the trainer, no crash at all and both overlays show up properly: Link and there are my settings: Link
Still the fatal crash in your screenshot comes from the MSI overlay. Maybe its an older version of Afterburner? Maybe a specific setting?
I didn't know the trainer had an overlay with it. First I turned off rivia statistics, and it worked as advertised. Then I tried the trainer with it's overlay off, and the rivia turned back on. It worked fine. So apparently there is a overlay conflict between the two. I'll just stick with the rivia overlay for now for the info it gives me. Thanx for the insight on the issue...
