Update is necessary before transmitting return

When I select "Transmit Returns Now", after thinking a few seconds it returns a popup that says "There is an update available for your version of TurboTax.  Before you can file electronically, you'll need to get this update.  To do this, go to the online menu and select Check For Updates."

 

Before I started my return today, I did the updates.  When I go to the online menu and select "Check for Updates", it tells me "Your software is up to date."  But then when I select "Transmit Returns Now", it gives me the same message as above ("There is an update available...").  I'm caught in a circle.  Can you help?  I've already paid on-line for my state tax return.  I'm using TurboTax Home and Business.
