Remote Access Manager crashes when I click Reporting

Hello good people,

I have been using reporting for Direct Access for a while without problems.
Now, when I click Reporting it throws an execption:

Problem Event Name:    CLR20r3
  Problem Signature 01:    RAMgmtUI.exe
  Problem Signature 02:    6.3.9600.17725

  Additional Information 4:    dac2b69a4b166e2929a07381a6a9f7ed

There's also a  Application error event ID 1000 (faulting module KERNELBASE.DLL) followed by a .NET Runtime error event ID 1026

I did some research and found out that this might be caused by a courrupt or damaged .NET installation.

I ran the .NET installation verification tool without any problems so .NET seems to be ok.
Any clues to solve this annoying problem would be greatly appreciated.
