I checked this out today. All is as DennisG says it is. Payables is linked to Adagio Job Cost, not ACCPAC JC. The @JC81C files match the dates you gave us. There are no @J65AJOB files in the \softrak\dict folder which is probably why Adagio is giving an error. But why is Adagio looking for this file instead of the Adagio JC 8.1C file?

This error appeared with the Payables 8.1F update. No problems before running 8.1E.

I have a call into Softrak Tech and I sent an email with some screen shots.
