The first step is to sync the time on your machine to the network time by following the steps below.

Synchronize with an Internet Time Server:

• • Right-click the time on the taskbar and select Adjust date/time. 
  • In the Date & Time settings, make sure "Set time automatically" is enabled. 
  • Click Sync now to synchronize the clock with a Windows time server. 
  • If using older Windows versions or needing more options, go to Control Panel > Date and Time > Internet Time.

More comprehensive instructions on syncing the time can be found on this article.

If the issue persists after syncing the time then please contact our support team with information on the error you are seeing and the license key you are trying to access.
