Error after Studio 2015 SR2 update

Since the SR2 update I have been unable to open Studio.

Error message:

An unexpected error has occurred while loading the global plug-in services

Could not find any resources appropriate for the specified culture (or the neutral culture) on disk.

basename: Sdl.LCStudioIntegration.common.plugin location info: <null> fileName: Sdl.LCStudioIntegration.common,plugin.resources

Please advise
