The error message "Error opening file - Unable to create the new file" appears when the rip reaches certain tracks. It stops the rip until the problem track-files are unchecked. It has happened with a number of CDs. Express Rip performed OK to start with and the error messages only began to appear after I decided to buy a software licence. Now it prevents a few tracks on most CDs from being ripped.
The track-files that create the error message do not present a problem for Windows Media, and they work with the Play functionality in Express Rip
I have raised a support request but would like to know if anyone has experienced and solved this.
