Several weeks ago I created a form with version 8.2.1. Everything worked fine. Went back into the form yesterday and could not save or view the form as a pdf. Log reported an error with version compatibility. As a test I tried to create a new form, same problem. Went in today to attempt another form and received the error "Failed loading Device Driver [pdfldriver. System error [%1 is not a valid Win32 application" with no mention of the error from the previous day. Any ideas (in layman terms please) would be extremely appreciated. Thanks!
