This is basic VFP 101 but I am working on a project and from time to time I get errors about CAN'T LOCATE FILE and it points towards a VFP program directory with my screen, report, etc tacked on the end.

What am I missing here... all my calls are like:

DO FORM mainmenu

USE myprogdata

Eventually, this whole APP of course is going to be BUILT into an EXE.

Help!!! I know this is simple but for the life of me I can't figure out what I am missing and I looked through other VFP apps I wrote and nothing is coming to mind.
