Lightroom 4 camera profiles stopped working.

I have Lightroom 4 and that is what I use for doing the processing of most of my images.  I also have CS5 loaded and am trying out CS6, but it is causing me a problem.  Having CS6 loaded on my system causes the camera profiles in Lightroom not to work.  I purchased some profiles for my OMD, and they work great in Lightroom 4, but when I load CS6 onto my system with the newest version of Adobe raw, Lightroom 4 no longer shows my camera profiles.  Any ideas on how I can correct this?
