The major problem with the activation and registration system the authors of this product have in place is simple! IT IS A MASSIVE PROBLEM ALSO, IF THEY THOUGHT ABOUT IT THEN THEY REALLY DO NEED TO CHANGE THE WAY THE ACTIVATION SYSTEM IS DONE! The problem is: What do users do when they have say 4 or 5 activations on 1 key which they've bought and forget to transfer the registration, or maybe they cant because the hard drive died or they just re-installed and didn't think to transfer it! The activation system is flawed! Dont like it!
