Connections disappeared

I'm not the first this had happened to, but I can't seem to find the
solution in the archives.

I attended a web conference over lunch which had some suggestions on being
more productive in WDSC.

One item suggested was defining multiple connections to the same i5.  So I
tried it.  The 2nd connection (same i5) came alive with all the same filters
as the first connection, which I thought strange.  I tried to delete some
filters and got an error that I couldn't, as it was it use.

So I closed and reopened WDSC and voila' all my connections and filters are
gone.  Not a one left.  I rebooted and there's still nothing there.

So what happened to everything and how do I get it back?
