My 2 pennies worth... The new Security Scheme is different. Learn how it works. It's not the same as P4. It's new. In addition to your serial number you now have to get a unlock code from curiouslabs. It changes for every hard drive. You get three installs then you've got to explain to CL why you need another one from what I understand so far. Otherwise if you never change hard drives and your Windows OS never has problems then it's a nonissue. Many of the stability issues should go away as soon as CL issues the up and comming patch. Then everything'll be smooth again. I wouldn't be surprised if the comming patch even improves an already amazing product some more. :) :) :)
