Just a quick question

The KVStool is working with a systemcode in combination with a registrationcode.

I took the time last week to format my harddrive and installing everything from scratch after a severe systemcrash. It seems that the systemcode has changed? So as I'm correct one of my registrationcodes has become invallid after a clean installation?

I was wondering if it's not possible to get this systemcode connected to some hardware instead of the software? So when someone has a systemcrash he does not have request a new code

Just a quick thought
