Attempting to print PDFs fail with an compilation error. Plz assist....

Hi. I'm tire kicking RH11 / FM 12 with the trial copy.

On 3 or 4 separate documents, I can successfully print to .docx format, but I can't print to PDFs. When I try, the program quits with message just below. I've also attached the compbilation log, which ends with "Internal error encountered,  Failed to generate Printed Documentation. "

I can print the resulting .docx doc to PDF from Word. But that's an extra step I'd rather not have to take.

Any tips on what might be causing this PDF crash would be appreciated. I see that other's have had similar problems in the past, but its not clear if their was conclusion on their issues.

Thanks in advance.

Kurt
