Updating the software is different from Upgrading the software.
Software Update
Updates are higher versions of the software that introduce new features and/or bug fixes. Updating the software is free.
All are encouraged to update the software as new versions are released, regardless of what edition you are running (Standard, Designer, Designer Plus, Business).
Updating the software does not remove any upgrades from the program. Updating your software version simply applies updates to the software and moves the program to a higher version with various new features and/or bug fixes.
Software Upgrade
Upgrades are paid and purchased editions that provide access to additional software features.
If an upgrade is removed after updating the software, this is typically caused by file corruption in the license key folder. Re-applying the license key will bring back any upgrade features.
