If you get error messages during activation and cannot resolve it by yourself, you need to submit a reactivation request on license website using the following steps and wait for approval.

1. Go to the license website. Click the Reactivation button.
   
   
   
2. In the Reactivation Request page, input the serial key which has errors and click Next.
   
   
   
3. In the next page, click the Create button to create a new request. However, in case you have submitted a reactivation request for this serial key before, the last reactivation request will appear on the page which might be in progress, done, or expired.
   
   
   
4. In the Create Reactivation Request page, fill all the answers and click the Submit button to submit your request.
   
   
   This creates a new request. You can refresh the webpage later to view the updates.
