I have just downloaded a game called Puzzle Inlay & everything is fine except I can't save the game which means everytime I have to start anew.Evertime I finish a level & try & save it it says "inavlid filename".

I have Windows XP & I read on the net it could be due to the fact it's not compatible with my Windows XP.

It said to go to Properties>compatibility & tick Run this program with compatibility & I tried this although XP is not on the list.

Can anyone tell me what to do?
Thank you
