I link to .pdf files in Access 2003 and since upgrading to Adobe Reader X yesterday, am unable to link to these files. I receive an error stating "A problem occurred while accessing the OLE object". It goes on to tell me to verify that the file is where I say it is and that it is accessible, which it is. I can go to that file in Adobe Reader and open it.
Disable the protection mode in the preferences of Adobe Reader.
Thank you, that worked.
