I just purchased this May 2 from your site, how do I know if it needs updated again? If so do I have to uninstall the paid version first? I am a new customer.
He is referring to the free preview of DeskScapes, which is somewhat like a demo version. Since you have the enhanced version this update should not apply to you.
You can make sure you have the latest updates using Stardock Central or Impulse.
