I have Ptunes and UDMH on my 650. I need UDMH to play Doom, etc. However, UDMH causes a HUGE problem with Ptunes if you want to use the Napster to Go, Yahoo Unlimited, etc. service. You CANNOT have UDMH installed on the handheld when you attempt to listen to or transfer any tracks in Ptunes. UDMH causes Ptunes to not to be able to access the file that provides the license certificate. You MUST completely uninstall UDMH in order to listen to or download any of these tracks. A Huge pain, indeed.

Is anyone aware of a program that accomplishes the same thing UDMH does? Maybe it wouldn't interfere like UDMH does.
