Thanks, but the error msg is actually an Acrobat msg.
I called the Adobe Tech Support and spent an hour on the phone with the gentleman. We went through many configurations and I'm still trying to resolve this issue (I'll be reinstalling Acrobat X in a minute to see if our changes make a difference).
I believe the trouble lies in the fact that I'm on a 64-bit system, with an MS-issued security update. Hard to say exactly what the fiasco is all about just now.
