Dear User,
To avoid the problem please try to follow the instructions below:
1. Go Start > All Programs > AVS4YOU > Uninstall. Please make sure to click the "Check All" button.
2. Follow the link below and download the utility that will automatically remove all AVS software components from your PC. Save the utility on your computer and launch it. It is highly recommended to leave the default option "Delete license key-files" checked:

After that download and install the latest version of
AVS Video Converter and try to convert your files once again.
Inform about the result, please.
Kind regards
