I have bought a specialized program, an add-on to other software that I already own. The add-on program was protected so its serial key can only work on one machine. It was fine by me.
The problem occur when I upgraded CPU memory and the protection key no longer worked. It also asked a new key when I update my Windows XP. I have lost contact with the programmer as he/she never reply my emails.
So I need people who can fix this. I am not asking pirating the software because I have paid for this.

This is not clear how add-on you've bought is protected but I believe that fix won't take longer than 5 hours. One hour of playing with a software is enough to give more accurate estimation.
