[SOLVED] Unhandled Exception: System.TypeLoadException: Could not load type 'System.Runtime.CompilerServices.ReferenceAssemblyAttribute' from assembly 'sysglobl'.

Hi everyone!

Yesterday Unity crashed during a playtest.
Now I’m getting this error:

Internal compiler error. See the console log for more information. output was:
Unhandled Exception: System.TypeLoadException: Could not load type 'System.Runtime.CompilerServices.ReferenceAssemblyAttribute' from assembly 'sysglobl'.

  at Mono.CSharp.Driver.Compile () [0x00000] in <filename unknown>:0 

  at Mono.CSharp.Driver.Main (System.String[] args) [0x00000] in <filename unknown>:0 

.

I’m using Kinect in my project and some script which works with KinectWrapper.
In the Inspector, under every Script component, I find:

The associated script can not be loaded.
Please fix any compile errors 
and assign a valid script.

I cant’ find a solution to this…
Anyone could please help me?

Thanks in advice.

Solved deleting 2 dlls in the plugin folder
