I tried evaluation version of CodeRush, but still no luck :(
Last things come to my mind which can help to reproduce or fix this issue are:
-Close all VS instances, delete all community plugins except CR_SmartQuotes and see whether problem persist
If that didn't help
-Close all VS instances, delete (you may want to backup this first) CodeRush settings folder - on my machine it is "c:\Users\ProfileName\AppData\Roaming\CodeRush for VS .NET" and see whether problem persist with recreated default settings.
If problem will still persist, I am out of ideas.
