This error typically occurs when your system time is incorrect or when an ODM file for an audiobook was downloaded but not opened in OverDrive's desktop app.
Here's the full error message you may see: "Unable to acquire license to play selected title. The requested license is either invalid or already acquired."
Generally, this error can be resolved by setting your system clock correctly, then downloading the title again:
- Check your computer's system time, date, and time zone settings to ensure they're correct. You can usually access these settings by clicking the clock on your taskbar.
- Delete any saved ODM files on your computer.
- Clear your temporary internet files.
- Download the title from your library's digital collection again and open it immediately.
If the OverDrive app doesn't automatically open when you download the title, find the downloaded ODM file (in your "Downloads" folder by default) and open it.
If the ODM file still isn't opening in OverDrive's desktop app, you may need to change the file association for ODM files.
