SQL 2008 R2 Database stuck in Restoring... state after attempting a Full Restore

In attempting a restore the database, on a shared SQL 2008 R2 (10.50.2500.0) server, is stuck in a (Restoring...) state.

So far, I have tried running the script:

RECOVER DATABASE xxx

WITH RECOVERY

No help.

This is a highly utilized DB and is 3GB in size. The backup was just performed yesterday before attempting an upgrade of the application that uses it.

I was presented this in the "Related Topics":

and I'm wondering if it is the only route for me to take at this point?

Anyone have any better suggestions?
