Just tried to go from v4.04 to v4.06 and can't, at least not without buying a new license.
Is it usual for this company (NCH) to charge for fixes to the previous minor version?
In the change from v4.04 to v4.06 I find only fixes to the windows versions with the
exception of adding license classes to the latest version. Hardly a functional improvement.
Charging to fix your own software just doesn't seem right.
