MP locks up and some other weird behavior. (1 Viewer)

MP has been locking up randomly, even freezing my whole system. Now I am getting some weird behavior, for example, I get the following error when configuring the Pandora plugin:

Description:
  Stopped working
 
Problem signature:
  Problem Event Name:    CLR20r3
  Problem Signature 01:    configuration.exe
  Problem Signature 02:    1.2.3.0

  Problem Signature 09:    System.NullReferenceException
  OS Version:    6.1.7601.2.1.0.256.1

I have no idea where to start so any help is appreciated. I have attached all my logs.

Thanks for the help.
