Thanks support.

Data is all held in the same folder. We're running recent releases of IC (92A-180512) and GL (93A-180422). We are current on everything except for Receivables as 9.3A wasn't playing nice with a 3rd party add on we use.

I looked for the more recent files that you listed.
I do have a ICALBTCH.### file there at 0 bytes. The time stamp on the file is a couple minutes after the J/E PDF's were created in my reports folder (on Oct 31).
I also have a ICBRSCAL.###, it has a time stamp of earlier today and is 377bytes) in size.
