If you change more than 2 things, you'll will have to get a new serial.
In this special case this is no problem, since the user is in constant
contact with me (the seller) anyway. This is to keep him from using two
copies on two different machines which by the way ist in the first line
for his security, because the application sends thousands of SMS at his
own costs. So I have to make it as secure as possible.

Sure, but it would have to do something with the machine, otherwise one
could just copy the application, if he has the password.
