Can not generate Communication Diagram Report

A few weeks ago I was able to generate communication diagram reports…
The only thing that’s changed is that I’ve upgraded to the newest version of 4.1(the late-febuary build), and whenever I try to generate a report, any communication diagrams fail to be generated(without any sort of error message… they aren’t there).

Anyone know what’s going on?

Dear Evan,

Thank you for your information, we will investigate this problem.

Best regards,
