So, I bought my carvewright from my step-dad... I am trying to get the software downloaded onto my computer... but there are already 2 computers registered and I can't figure out how to remove or replace them! When I put in my computer serial number it says :

The following errors occured while processing your form input:
Unknown Serial Number or Activation Code Click here to return to account settings


HELP PLEASE I have a ton of projects to get started on and very little time to finish them!
