When I am rebuilding an APP or EXP through the Project Manager, I am getting the subject error. This is a project that I am converting over from VFP7 to 9. I have not modified the reports at all in 9, and my report engine behavior is set to 80. Why in the world would the Project Manager/Recompile All even touch my FRX/FRT files, and does anyone know why my report FRT files would become corrupt as they are not missing? TIA!
