How do you fix the “Authorization Error”?

The program can only convert DRM-protected files on an authorized computer. If you have not authorized your computer but import DRM-protected files, you'll get the “Authorization Error” message. In such cases, ensure that the authorization has been done on your computer. If not, follow the instructions below to authorize your computer.

For WMA/WMV files
1. Download and install the latest version of Windows Media Player.

2. Open the WMA/WMV files with Windows Media Player. 
3. Make sure the WMA/WMV files play well with Windows Media Player. If not, follow the onscreen instructions to authorize your computer.
4. Import WMA/WMV files to our program to convert to other formats.

For M4V/M4A/M4B/M4P files
1. Download and install the latest version of iTunes
http://www.apple.com/downloads/
2. Go to Store > Authorize This Computer in iTunes to authorize your computer.
3. Make sure the videos you want to convert play well with iTunes.
4. Use our program to convert DRM-protected files. 


For AA/AAX files
1. Download and install both iTunes and Audible Manager.

If the DRM-protected files play well with Windows Media Player, iTunes or Audible Manager, but the above methods don't help, please switch to a different account ( Administrator or Guest) to have another try.
