Connection Manager will not cooperate
Although I did finally get SharePoint 2010 to connect to FrameMaker, I'm having a terrible time with the Connection Manager. I cannot seem to re-enter a connection - only specify new ones. When I supply the details for an existing connection and click on Connect, I get this:

I know it exists! I want to select the titled repository, but Connection Manager apparently thinks its job is only to create new connections. What am I missing here?
Oh, when I open the repository manager, there are no repositories listed there. If I specify a different name in the Connection Manager, that will be listed, but of course that builds a new local path and any files I had checked out in my last session are not present in the new path. This will never do.
How do I open the repository that I've already had open and populated with files?
Edit: I've sort of figured out a workaround - when the Connection Manager comes up, if I Remove the repository listed there, then re-specify its connection parameters, it will finally open. This couldn't possibly be the way it is supposed to work, based on the instructions in the Help file. I'm a little leery of doing things this way - I've already lost some data because of this. Ideas anyone?
