Any luck figuring out how to delete Kinect Me and Googly Eyes? I seem to have the same problem as you.
As for starting Fun Labs, what i do is search Bing for Kinect Fun Labs (I use the voice prompts). Go to the general Fun Labs add-on and then choose to redownload and then hit play now. Which seems to be the same thing that you do but from a different menu. This is the only way that I could figure out how to start it.
EDIT: Also posted in your Kinect Me thread
in hopes that you see one.
