Did you use the Removal Tool (MCPR after deleting your McAfee software from your Control Panel/Programs and Features?
Then I suggest you do so/Restart and go to your account and try again.
In other words install your software from your account.
Product keys can only be used once. After that you must go to your online account to download the software.
