When I returned from a weekend away I can not longer open any type of file in my Groove 2007 workspaces. I can open the workspaces and copy files into them, but if I try to open a file I get an error that says "the file cannot be launched." I have all of my work in Groove, and even though I have a laptop with my account on it, I would sure like to figure this out on my desktop. I did a disk check and defrag and that did not fix the problem. I am running XP and Office Ultimate 2007.
