I have an FP2.6 report that has been running since 1996 and suddenly won't run and I can't maintain it - in either case I get an error "Report File Invalid". I tried copying the .FRX and .FRT from my computer (where it workds fine) to the user's where it is not working. This did not solve the prolem. What causes a report file to be invalid? Is there anything I can correct by opening it as a dbf? The report is excluded from the project so it would seem copying in the orignal would fix it, but it didn't.
