TypeLoadException was unhandled by user code

Couldn't figure out why this is happening.

System.TypeLoadException was unhandled by user code

Currently have JustMock_2013.2.603_Dev.msi installed.

Hello Joel,

Thank you for reaching our forums.

Please, make sure you have updated the Telerik.JustMock.* DLLs (inside your test projects) after the installation of our latest internal build (JustMock_2013.2.603_Dev).

I hope this solves the issue.
