My Mac Partition Won't Work

[scoutcrafter]

Two months ago I partitioned my Mac to hold Windows 7 so I could play SWTOR. I'e been playing it since I got it. It's been working fine. I've been switching between my Mac and my Windows Partition fine. Until about a week ago. Now I can go to my Windows Partition and play the game as normal, but if I try to get into my Mac Partition, It just sits there, as if loading it, at the white screen, forever. It's a neverending load. Is there a way to fix my Mac Partition without deleting everything and starting over?
