Hi svenster, that seems to be some problem with the Winlicense anti-hacking mechanism that the 30-day trial version is protected with.

If you try the other "no save" trial version on the download page (http://moi3d.com/download.htm), that should work for you since it does not use WinLicense.

For v3 I'll be putting out a new version of the 30-day trial with an updated version of WinLicense, hopefully that should solve whatever problem is happening there.
