Zbrush 4R4 Now Crashing!!

After I transferred over some materials, alphas, and brushes from 4R2b to 4R4 I noticed that Zbrush kept on crashing every time I open a certain project file. The problem still exists after I deleted everything that I added and even after I updated to the new patch.
Does anyone know what I can do to carry on with this file or do I have to go back a file and redo everything? Any idea on why it started crashing on me?

Thank you!!!

It’s likely that the project file itself is the culprit, from the sound of things. Are you running 4R4, or have you patched to Update 2 (in which case the title bar will say 4R4 P2)?
