Every time I restart the computer the game says it is in trial.

Workflow:
1 - I played some days in trial
2 - I purchased the game on the windows store
3 - I played the game
4 - I restarted the computer
5 - The game says it is in trial and it is expired

Current workaround:
If I "purchase" the game again the windows store detects that I already own the game and produces an error. After that the game is again in full version.
