Godfrey, VFP projects are stored in normal VFP tables renamed to a .pjt extention. The table has an associated memo file renamed with a .pjx extention. These files can get corrupted like any VFP table. There are several file repair utilities, some for free, some not. For example, see

ATFixDbfFpt 1.5a, all xBases supported. File #9930

and

Crashed tables rebuilder File #9264

and

You could also try to open the .pjt file in the same way as opening any dbf file. Open it in exclusive mode and try to PACK it. This might work. If not, try one more trick which is open the .pjt file and COPY TO .... another file name. Then see if the other file name will compile. If so you could rename the new file and its memo file back to the original .pjt and .pjx file names.
