I appreciate your dilligence here, but the problem was not in the code because it worked in the past and now works again. I even a created a new access database with one table, one query, one form and one button to run and export the one report. There was one line of code on the click event:
DoCmd.OutputTo acOutputReport, "Data", acFormatPDF, "PathToFile.pdf", False
I have noticed that Access 2010 is a little unstable. When creating an mde from an mdb, Access will often stop responding and crash. After that happens, if I relaunch the application, I may not be able to view code behind any form without crashing the application again. In those cases, I will have to open the database in Access 2003, compact and repair, and then try to open it again in Access 2010. Anybody else have that experience?
