This problem appears to be fixed now
It looks like this issue is now fixed.
I actually installed my Gamer's Gate version of Crossworlds in the Windows 10 Technical Preview and I didn't have any issue.
So I rebooted to my Windows 8.1 and it just launched without any problem so I guess it got fixed sometime in the past (maybe a Windows Update?).
I actually now can tri-boot between Windows 7, 8.1, and 10 Technical Preview and so far Windows 10 seems like Windows 8.2 to me. I'm in Windows 8.1 probably about 95% of the time right now, but it is nice to try out the preview to ensure that there won't be any problems in the future with the games I play now.
