I would appreciate if you would not just change the licensing info of our applications. Patchstickbuilder has been solely developped by us without any reference to ATVUSB Creator. If you want to fiddle around with licenses, do it with your stuff !
You cannot relicense code you do not own.
I can see parts that are derived for other projects. Your license is restricting the usage of these parts to the point of violating their own license. If all of the code was your own, then your license would stand, but the fact remains it is not.
