Problem with MarketPress database update

I updated the WPMU plugin Marketpress this morning to version Version 3.0.0.7. I wasn't surprised to see the same message I see every time I update Marketpress:

MarketPress requires a database update to continue working correctly

So - I click on the link, then click the update button. Get an "update complete" success message so I go back to what I originally logged in to do on the site. Unfortunately, I'm still seeing the beg notice at the top:

MarketPress requires a database update to continue working correctly

So - I do it AGAIN - and again The message won't go away. I decide that it's a Chrome problem and try working in MSIE. Unfortunately, I'm getting the same message there as well.
