Some of my rules are not working

Just recently some of the rules have stopped working in R# (I'm on 4.5 in VS2008 working in C#).  For example, unused private methods and unused parameters no longer show up as gray.  I've checked ReSharper -> Options -> Code Redundances -> Unused Declaration -> Private accessiblity and it is set to Show as Warning, but I'm not getting the warning.  I've tried:

• Creating a new project
• Repairing my installation
• Uninstalling and Reinstalling R#

I'm at a loss for something else to try.  I'm not sure which rules are working correctly and which aren't which is very stressful as I rely on R# as a backstop for a lot of stuff.  Not being able to rely on it working as expected is a big problem.

Thanks for any help.
