If the backend is installed (as it was for me, I simply upgraded GC) then you might need to modify the environment file in the 3.0 app’s bundle. Look in this month’s archives on the list for a post by me on the same topic. I didn’t get a reply, but I found that solution via a bug report that JohnR offered. Sorry I don’t have the link handy or the info on the tip of my tongue to save you the searching trouble.
