Today, I got to walk a patron through deleting her DRM folder. First, she told me her error was "Parameters are incorrect". From there, we found that she had Windows XP, and that it's a fairly common error.
To fix it, I googled it. "Parameters are incorrect overdrive". One of the first links I pulled up was this: Fixing: error 0×80070057: The parameter is incorrect for OverDrive media console .
From there, they'd posted what Overdrive tech support has posted to several people. Below is a quote of the fix for "The parameter is incorrect".
We are sorry that your patron is having difficulty downloading OverDrive Audio Books. We think the error they are receiving can be resolved by resetting the DRM (Digital Rights Management) for Windows Media Player. Please ask the patron to perform the following steps to reset the DRM and let us know what results they get:
1. First, please delte the DRM folder on your computer. Depending on your OS, it can be found in different locations:
* Windows 2000 and XP: C:\Documents and Settings\All Users\DRM
* Windows 98: C:\Windows\All Users\DRM
* Windows Millennium Edition: C:\Windows\DRM
If you cannot find the folder, it may be ‘hidden’. Please use the following steps to view hidden files and folders.
* In Windows Explorer go to Tools > Folder Options > View
* Under ‘Hidden files and folders’ heading, make the following changes:
o Select ‘Show Hidden Files and Folders’
o Un-check ‘Hide Protected Operating System Files’
* Click the button ‘Apply to All Folders’. This will ensure the changes affect all folders on the system.
2. Re-run the Windows Media Player Security Upgrade from the OverDrive Media Console under the ‘Tools’ menu.
3. Attempt to download an OverDrive Audio Book.
We apologize for the difficulty. Please let us know if this resolves the error or if the patron requires further assistance. Thank you.

So if anyone runs into this problem, I hope this helps. It worked for my patron who hadn't been able to download several different e-books.
