Groove Calendar is blank with no tools and no calendar

[Stranded in Minneapolis]

This is happening on one machine. Everything was fine and then tonight I
started getting all kinds of Groove error messages (non-responsive) and ran a
diagnostic which came back "no problem found) for every item. I try to go
into Discussion and get an error message "you must be logged into groove to
use this tool" when I'm already logged in. Restarted Groove, deleted the
discussion tool after numerous failures to enter it. Recreated the
discussion tool and now that is fine. The calendar tool remains blank
though. Any ideas?

Is this happening with all of your spaces or just one? If it is just one,
then how many people are in the space and how active is the calendar tool?
