When Konvertor 4.0 () was released they changed the length of a license (including EXISTING) for customers at the same time.
When it was bought all UPGRADES was free (i.e including major versions), both the
front page and FAQ said so, although the faq was more direct.
Quote from the old faq: "Do I have to pay for the upgrades? No! All upgrades are free to registered users."
ReferenceThe new faq says: "You will have to pay a small fee for main new versions (10 €). Bug fixes are free, sub versions (4.01, 4.02 -> 4.09) too."
ReferenceThis applies to old customers too.. in other words, they did the same as selling a Windows 7 Ultimate and after some time it reverts to Windows 7 Starter. (I know the comparison isn't exactly spot on).
Well, the software wasn't too good, but it still doesn't seem right.
