Ok guys I have a fix for those of you that either put the wrong serial in or upgraded from an old version of Coreplayer. Simply replacing the file that stores the serial will only temporarily fix it. The problem is that when you go to settings and remove Coreplayer it leaves behind a file with the serial info. So what you need to do is uninstall Coreplayer. Then go to fileexplorer and open the Application Data folder and delete the Coreplayer folder. Then reinstall Coreplayer. Now when you open it, it will ask for a serial. Put the right serial in and it will be fixed.
