Hi,Shiu:

Thanks for your excellent work on spine to make it become such a great animation creation toolkit.As a programmer,I traced the license security part of your program this morning(just for fun,don't worry,I have bought pro license last Monday > ).The result really impressed me.I don't mean your program is not crackable I mean I really like its mechanism.Robust and integrated with update logic.Only the program content downloaded with valid license plus JVM byte code hacks could break it in some way. :yes:
I suggest you make a little bit change for the license code storage.It's stored unencrypted in registry.I suggest you store it encoded.Because I cannot stop the animator take the code from registry and use it to register for another copy(Assume there is one animator seat in studio but the worker is floating sometime,which comes from different outsourcing company).So store it in an symmetric encoded way would be safer to license owner and won't affect your server get the real license code content.
That's the first suggestion.

And along with the trace result.I searched google for people that have done same thing like me.I found thread on CGPersia which I believe you already know what happens there as you made the reply posts.I don't wanna talk about crack itself.I wanna talk the license model.I found many guys says they cannot get the full feature tested in trial version.And many guys are more complain about the price is too high(And you replied with the efficient-cost formula for them).To me,I really not satisfied with the trial version experience.I recommend you consider about a rent-like license model.A cheaper but time limited full feature license.For example,15USD for use the pro license feature for 1 month.And 249USD for life time.This would lower the cost for those penniless indie developer to have the opportunity to use this awesome tool to finish there early project at the low cost.And it would bring you more users that have real practice experience on the full edition spine contrary to the trial edition which is useless to learn the whole workflow from content creation to applying to game program.

That's all.Sorry for my terrible English.Hope you will get the key point.And hope you will keep surprising us with awesome feature in future.
