System.NotSupportedException error in UDK:

An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

the second Tip helped me even though i have Windows 8....

Yes, I figured how to fix this bug.

I have found a fix.

Step 1: Go to where you have placed the SDK files. Navigate to the 'Binaries' folder.

Step 2: Find 'UnrealEdCSharp.dll'

Step 3: Right click and go to Properties.

Step 4: At the bottom of the newly opened dialogue, it will say something about how it may be unsafe. Click the button to unblock it.

And voila, it works! You can now open the editor without any issues.
