Hello Scrumpi,

First of all, I will move your thread to the place where it should be
Regards your concern, you don't need to worry as, if you will buy subscription before making new PC, and even if an error will shows up, just come back here and make a request on special destinated forum category for HWID change, just simply explain there why you want HWID change as you explained here and it will be sorted for you without any problems

Kind Regards
