I installed Nexus 8.5 Rev 3 and I am having problems with all my workflows working. I would say 60% of them work the other 40% do not. When I go to flush them from my stitcher monitor they instantly bomb out and give me the following error: Activity Interpret PS/PDF Module Interpreter Description Undefined Filename-%%[ Error: undefinedfilename: OffendingCommand: run ]%%. I have two approvals and some workflow work to each machine and some do not. The age of the workflow also means nothing. I have older and newer ones that work and some that do not. I have also gone and restored from different backups.
