Enter your license code into the form and submit.
Your current key status appears below the form. A Reset button appears if there is any computer assigned to the license and more than 1 week elapsed since the last reset.
After clicking the Reset button, your license will be detached from ALL of your licensed computers. After this step your license count is restored to full capacity as if it were new, and your computers switch to non-licensed mode (trial period every 3 months).
Re-enter the code to indicators on those computers, where you need the full license. You do not need to interrupt the working ones, just attach an additional indicator for a moment, with the code filled.
