Thanks a lot!

You didn't specify which log file I should post.

This is the Z12demo.log:

AUD/USD Trade 12 not found

Doesn't look useful to me? I checked the other logfiles and didn't find something that looks crash related. Deleting the *.trd file solved the problem temporary. The system is running stable hardware and operating system wise.
