I have just upgraded to KeyShot 3.0, quickly followed by a ungrade to 3.1

I now can't link from SpaceClaim 2011+. It removed my Keyshot tab.
If I want to render my parts I need to export and then import.  What a hassle.
Any ideas as to how I get my KeyShot tab back?
keyshot say itis a SpaceClaim problem

 Unfortunately the keyshot 3 plug-in is not availabe with SC 2011+. This is fixed in SC 2012 which is set to come out in a couple of weeks.
