I have 64 bit Windows 7 and Media Player 12, fully updated. Downloaded and installed Overdrive Media Console and downloaded a WMA audio book from my local library. The audio book will not play on Windows Media Player or using the Overdrive Console. Media Player indicates there's a problem and refers me to a web site which did not really address the problem.
I've done web searches and tried everything that has been suggested, including changing option settings on Media Player and using Internet Explorer to download the security update for Media Player (which is apparently required to play DRM files). Nothing has worked so far. I have no problem playing songs or viewing videos using Media Player. The audio book was definitely downloaded as I can see the various chapters under the "My Media" folder under Documents.
Any ideas or suggestions on what I might try. From looking at various web sites, I suspect the problem might be related to DRM rights, but I'm not sure.
