ANGRY BIRDS SPACE RAGE

So, I got the new Angry Birds game, Angry Birds Space, on my Mac. It's awesome and by far the best of the Angry Birds games. If you don't have it, get it. It's a great game. 
 BUT, the other day, I went to open the game, and it said something about "Restore Windows". Apparently, last time I played I didn't exit properly and now it asks me to restore some window. Well as I went to click don't restore, it "unexpectedly quit" before I could do anything. I'm like "da f*q?" and just open it again. Same. Again. SAME. AGAIN. SAME. AGAIN. "Do you want to try to restore it's windows again?" Then I threw the computer out the window.

Ok, not really, but I got pretty angry(almost as angry as a bird. *ba dum tiss*)

So, my sister later logged on her user in the computer, and then she downloaded the game. IT WORKED FINE IN HER USER AND NOT MINE. Long story short, I spent most of the morning looking for ways to fix it and tried EVERYTHING but NOTHING worked. IN CONCLUSION, if you have any tips, please tell in the comments, thanx :D
