I read in this forum someone else had this same problem, developers left a link for them to redownload the program from and that solved the other persons problem. That link has since expired.
I replied to their post and said that I'm having same issue but have never received a reply so trying one more time. I use VR anyway which is why I downloaded the trial version. But if I can't use it, oh well. Thanks for any info you can help with. PS: I posted my log.txt file under my previous reply/comment in the other topic on same issue. Link to it below...

Press alt+tab when in the cockpit and the menu should appear.
