Upgrades are free for any versions that have the same major revision number. For example, if you were to license version 3.0, then
any subsequent revision that has the same major revision number would be a free update. This would include v3.01, v3.1, v3.5 or any
v3.xx. The program files are identical for the licensed and trial versions of the programs.
The process to upgrade is to download the trial version and install it into the same folder as the licensed version. The presence
of your previously licensed version will license the new version.
This upgrade process will not work if the trial version has a new major release number (i.e. version 4.0). In the event of a new
major release (i.e. v4.0), an upgrade fee will be required.
