pet shop hop doesnt save

I purchased this game and every time I load the game you have to start from the beginning this is very annoying and I am very disappointed with this game, has anyone else had the same problem with this game on mac os ?

I had the same problem and it is VERY frustrating having to start all over again every time....however i fixed the problem by first copying the game to a disc(i had downloaded straight to my computer) then i completely removed the game and re-installed it from that disc...it works perfectly now.............if I could only get beyond level 41
