Why wont my ZPR file open!?!

When I try to open my saved ZPR file, (one that I created and saved myself) I get a message that reads; ZBrush Executables has stopped working-Windows is checking for a solution to the problem… And then after a few seconds it reads; A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. Is there something I’m missing? I’m new to ZBrush so I’m hoping its just something simple like a setting I havent set correctly or something like that. Please Tell me this is the case.
