No need to reinstall, this is a common error that is thrown when Corel's anti-piracy service is not running. It is called Protexis Licensing
. Go to your Computer Management, Service and Applications, Services
. Then scroll down, find Protexis Licensing, or if you may have it installed more than once, in which case it might be Protexis Licensing V2. Check to make sure it is started and running. If not start it. This service must be running for some of Corel's latest versions to launch..
