A problem.

I use PSP 7. I was trying to turn some image stamps into brushes before and PSP froze on me. I did the typical CTRL+ALT+DELETE to close it, and reopened the program later to give it another try. Now when I try to open my brushes, it gets to 96% on the cache status and then I receive the the following error message:

Any help in fixing this would be greatly appreciated. I'm going nuts without access to my brushes. :[
