I never got a reply from Media Monkey, so I uninstalled and reinstalled MM, then followed the advice lowlander gave in a subsequent thread - "Try renaming d_iphone.dll to d_iphone.dll.off in the Program Files\MediaMonkey\Plugins folder. Does it resolve the issue?" This worked.
"Try renaming d_iphone.dll to d_iphone.dll.off in the Program Files\MediaMonkey\Plugins folder. Does it resolve the issue?" This worked worked for me also.
I had upgraded from MM3 to MM4, and it worked OK. Then after I did some house cleaning (uninstalled some apps including some Android remote control software), MM4 would no longer load. I'd see the splash screen, then it would dissappear and the MM process would stop.
I'm having the same problem. I upgraded from MM3 to MM4 and after a bit of reorganising a few albums and syncing with my Ipod, MM now won't startup, just the flashscreen then nothing. Unlike the others I haven't uninstalled iTunes, I wasn't intending to. But I am syncing with an iPod Touch so I presume I can't rename the d_iphone.dll to d_iphone.dll.off ?
I was going to try reinstalling MM but it sounds from others in this thread as though that isn't going to fix it....and I don't want to loose all my playlists yet again.
I'm not entirely sure how things are with 4.0.6, but older versions did require QuickTime for iPod/iPhone sync. A corrupted QuickTime install would then cause issues and this often happens when it gets uninstalled.
