Remote console crashes when I move workstations between PGs

Question

Hello,
I have an SCDPM 2012 R2 UR2 server (4.2.1235.0). I manage it remotely using DPM console installed at my workstation. We use client protection to protect files from some of users workstations. When I move a client between two client protection groups, my
remote console crashes and I see an errors in Application log:

Where "PCNAME" is a name of workstation I moved between PGs BEFORE current move. i.e. I moved "PCNAME" then I'm moving "PCNAME2" and receive console crash with "PCNAME" in logs.

What operating system are you using? What processor does your computer have, how much RAM do you have and how much free, clean space is on your hard drive? When did you last run Disk Cleanup and Disk Defragmenter?
Have you ensured that you have the latest version of Quicktime from Apple.com?
What model of camcorder is your video coming from and what format and resolution is it?
When you add the video to your timeline in Expert view, is there a yellow orange line along the top of the timeline, above your clips? This would indicate a mismatch between the program's project settings and your video specs?
