Hi,
Mass storage addon interfere with WMDM it is suggested one or another.

if decide WMDM make sure that there is multiple duplicated profiles (eg. delete those that you do not use anymore) and that profile is enabled.

I am new to media monkey. I ripped my cd`s to media monkey and want to transfer to a usb drive. I plug in the usb, then on MM I go to options/Portable device sync and I see wmdm listed under plug in file. I also downloaded the mass storage add on. When I select either of these and click on "configure", nothing happens. What am I doing wrong? Thank you for any help!
