On every new project: Value cannot be null. Parameter name: instance

Trying the trial of the Telerik suite for WinForms in Visual Studi 2013, but any time I try to make new Telerik winforms projects I get the same error message when trying to open the form: 

   To prevent possible data loss before loading the designer, the following errors must be resolved:              1 Error         Why am I seeing this page?             Value cannot be null.
