love this game very addicting but..

i downloaded this game for my iphone loved it so much i bought it for my Mac, and i still love it except im getting really annoyed because the game says i have over 50,000 coins for the shop but when i go to buy anything it says i dont have enough. I have no clue why its doing this but i hope it fixes soon.. anyone else have this problem? (will change my rating when bug gets fixed)
