Ah, well thank you for looking into it.
Updating graphics drivers and trying different page file sizes has had no effect on the issue.
But the trainers still work separately as long as I have an offline key installed, as they recently stopped finding your servers despite adjusting the DNS settings and whitelisting as others had suggested. So I will just give up on trying to use the manager software for now. When I see the next version come out I will give it a try to see if there is any change.
