I have found the solution! I used the help function from my libraries e-books section and I got a response from OMC. I just tried it and it works!
Here is my question and the response:
Prior to the iOS5 upgrade, I was able to download WMA files to my PC and then transfer them to my Apple device using the transfer wizard in OMC. OMC indicated that they are aware of the problem and plan to fix it with a newer version, but it has been three months and the problem has not been corrected. Do you know if they are even still planning a fix? thanks

Once you have transferred a WMA audiobook to your device, a playlist will be created for the audiobook. Please note that WMA audiobooks will not be listed in 'Audiobooks' on your iOS device. You may need to take the following steps to move parts of the audiobook to your playlist:

2. Under the 'Devices' sections, click the arrow to left of your device to expand the contents view. The list expands to display the 'Music' and 'Books' categories on your device.
3. Click on the 'Books' category under your device.
4. Drag the parts over to the playlist created for the audiobook, which is also located under your device name in iTunes.
5. Verify that the parts are in the correct order.
