Your error above is explained in the Manual, click the Help Menu, Read Manual.
This problem is due to one of the .cdg files you are using being corrupted. Delete the files in the Songlist, and then put 1 file in at a time, clicking Test Write until you add the file that gives this error message. Once you find this file, delete it, so that you will no longer have this problem.
