Thanks for the responses, guys.

I am running both CW5 on one machine and CW4 on another, but I can see nothing pertaining to Workflows, Hotfolders or Virtual Printers in either one.

It also appears that our Fierys are H1, running System 8e Release 2, version 2.0, which I am guessing is probably very obsolete?

I'm beginning to think that this is most likely the root of the problem, and some FOC upgrades for the server software, Hotfolders and the Mini Graphix Kit would go a long way to getting things ticking over nicely again.
