Of course I'm having this issue now when the extensions are due for pass through entities.  I have proseries professional 15 free business returns and unlimited basic.  All federal business entities have either been filed or extended.  All are MD entities with a due date of tomorrow.  I'm trying to extend those returns but ProSeries wants me to pay to authorize them.  I tried updating the license with no luck.  I did just do a Windows update.  Not sure if the updated created an issue and wiped out the ProSeries license information.
