DPM 2012 R2 console crash after RU5 install

Question

Hello all,
recently I update my DPM to RU5 and since then then I click on management tab the console crash.
I tried Islam's solution but it is not working for me.
In the event I get this:
The description for Event ID 999 from source MSDPM cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
An unexpected error caused a failure for process 'mmc'.  Restart the DPM process 'mmc'.
Problem Details:
