Actually, that thread has more to do with individual scores not appearing on the leader board than it does with the ability to refresh the game's statistics. The "Update failed..." message merely indicates that the game can't connect to the stats server, and one's Internet connection is only one link in the chain.
This answer in our Support FAQ lists all of the possibilities. What prevented refreshing stats this time was that the database table had an error, which I just fixed. Refreshing stats for VV1 is working again.
