That fixed it. For some reasons, it didn't update the SP2 beta to the final version. Thank you for the help.

>>I did a lot of research and finally I found that for some strange reason Foxpro tries to open the report form from the development path! If I test the same application on my development machine the error disappears. If I remove the report files from my dev computer, the error shows up again. This is happening only when I'm using a report v9.0 (Set ReportBehavior 90).
