Peculiar message while trying to create new file in VS2010 Ultimate

Hello friends,
I have just installed the most up to date MVC package (Q2.2012.2.607).
When trying to create a new file in VS2010 Ultimate, all these peculiar messages appear.


Microsoft Visual Studio
El archivo vstemplnte hace referencia a la clase dc asistente
I did a "clean" install – deleted all Telerik installations, deleted %applocal% Telerik folder, deleted Common7IDEExtensionTelerik folder, did a clean install of the latest version, but the problem persists.
MVC3 projects run normally.
Do you know what I can do?
Thanks to all.
