Knowing of my success wont help any, but I downloaded 2009, tried it out some, enjoyed the view some then tried Contentmanager. I have trs2004, trs2006 and trs2009 installed and I can use either 2006 CMP or 2009 CMP. I have not edited any content though.
Perhaps you can launch either TC-CMP or 2006-CMP from their Bin folders?
