I have a Sansa m240 and I can´t use it in MTP Mode. Everytime I plugged in the player, the PC recognize it as an MTP Device but the installation process stops before it finished and tells me “The device may not work properly”. In other words, the installation process never complete, and the MTP Device is never fully installed. Of course WMP11 doesn´t recognize the device, so I can´t do much. It works perfectly in MSC mode. I have WinXP SP2 with WMP11, the wmp11 came with the OS, so I never had wmp10 installed, just in case it has something to do with the MTP.
What I can do??
