Hello, we've reset your Parallels Desktop license key, please check the issue

 

Also please note that Parallels Desktop 10 doesn't compatible with the lates macOS version.
Please check this out for more information.
Moreover we recommend to make a backup copy of your virtual machine to avoid any data losing.
