I installed my license and OOTPX ran fine until I quit...

...but when I re-opened it today, it was back in "demo mode" and I couldn't access anything! I tried re-entering my license key, and it told me it was already in use. Well yeah, because I activated it yesterday! What do I do?

Did it ask you to re-enter your license or did it say it was unlicensed? Do you have the latest build of the game? You can check this in the top left of the starting screen. Also make sure you have read the FAQ at the top of this forum as it can help with most issues.

If nothing helps, use your second license to start the game again, then post back here telling me what you have done. I can then use your second license to see why your first one failed.
