CAN NOT VERIFY GAME - AFTER GAME CRASHES

I played the game for about 1 HOUR!!

Then the game crashed at the end of the dungeon - WIN / SIEG - then CRASH

After this i had to restart the game and now it calls: it cant be veryfied the game - so it tells me that I AM NOT THE OWNER!??

I PAIED 30 EUR for the game for 1 HOUR - then the game says me I AM NOT THE OWNER????
