Overdrive Media Console - updated Fuze firmware and can no longer download audiobooks

Hi, I have a sanza m250 and I’m getting the same errors when transfering wma books in overdrive media console. I first formatted it in My Computer and got an error saying it didn’t support wma format. So I installed the sdmx3-iv001 exe file and that didn’t help. I can add mp3 audio books using overdrive media but not wma. I also tried doing what you suggested in windows media player by adding a song to my mp3 using windows media player then trying to transfer a wma book again using overdrive and get the same error… I am using windows 7 and my m250 doesn’t have a clock on it to set the time. Can you help me?

thanks in advance
