Reinstall your drivers using our program, CopyTrans Drivers Installer (free). You can find it here (see the bottom of the page): https://www.copytrans.net/download/

CopyTrans Drivers Installer will ask you to uninstall iTunes: this is a one-time procedure that we do to reshuffle the drivers' components. After you have done that, you can install and use iTunes again: your media library won't be affected.

If the issue persists, please contact our Support Team at copytrans@copytrans.net and send us the log files. Here's how to generate them: https://www.copytrans.net/support/preparing-log-files-to-contact-support/
