John,
you should be able to recreate your project from scratch if you delete your corrupted pjx table and the other project files, create a new project, add your main program and rebuild all to get all of the code related stuff pulled in automatically. Then most likely only have to manually add include files, graphics, and possibly some prg's if you use a lot of prg-based UDF's.
