The client (version 2.1.9) only works on some of my computers.
I have several computers running Ubuntu, Windows 7, or Windows 8.1.
During my initial testing I only used one computer that ran Windows 8.1, the client worked flawlessly with it. However now that I am installing the client onto more computers most of them open, show events, but they display "open error:Invalid data found when processing input".
In the case of the computer hosting the Bluecherry server it just says "error" nothing more.
