Just my 2 cents on the experience of the maintenance plan. I have 9 licenses since 2013 and have paid for maintenance every year including now. Their agreement states it includes upgrades and support. I can tell you that up until this year the support has been awesome but now it is crappy as crappy it can get. Must be new leaders in the support management. They will not honor the maintenance upgrades any longer. When sending in a support ticket with screen shots they ask for something totally off the wall that has nothing to do with the screen shot.
I don't understand why they are not supporting paid maintenance anymore that meets the terms of the agreement. I would think twice before spending money on annual maintenance.
