Mana Games

Hey Manutoo and the rest of the Forum,
I just ordered the game, downloaded and installed it but if I try to play the worldseries i get the bug 531, Data invalid, please reinstall the game. I did not mod the game in any way. It does not matter whether i use 3d or 2d courts. The only court working is the US Open one, which you can already play on in the demo.
Help is needed

Thread can be closed, the reason was an 'Umlaut' in my last name which wasn't put into the key correctly. Now everything works, thanks for the game
