New 3DFA registration policy
Obviously the thread was closed or locked because of the negative feedback, which i believe to be understandable, both for you and the users. You because its not what you need and for the user because thats not what the need either.
As some, i am against the idea of paying again for something you said to be with free updates.
The legal implications on the issue would not stand up for long after you have said free updates for life. I think you will find that you are now obliged to provide ongoing free updates to existing customers. On the other hand the new policie would not be a problem for new customers.
I understand you need to make a living as does everyone on the planet. And i can't see a way out of this for you. The best bet is for you is to have 2 versions, but even then you will have problems because if you concentrate on version 5, you will then get the regulars moving over to swift 3D or other, because 3DFA is probably one the worst documented programs on the net and is less likely to have futur updates.
Imagine you bought a new car and it broke down, you take it to the garage get it fixed and then discover that your insurance company decided to change policie stating that they no longer want to honor and respect their own word and contract. You would be highly peed off and take them to justice for your rights.
Its a similar situation here, you are out of order. Not only do i refuse to pay for a new update, but if i don't get the updates as stated when i bought the program then i will take it further both legaly and over the internet.
I reclaim my rights to free updates for life.
