I was running MP1.2.2, installed the skin on an existing install, and i ended up with MP crashing every 5 minutes. Completely uninstalled, reinstalled MP1.2.3, installed the skin FIRST (and let it install the plugins for me), then updated the plugins from extension manager, and now its running fantastically.
I'm not sure exactly what in the skin package caused all the crashes (possibly because i was running newer versions of the plugins it has bundled), but i will say again, this skin is definately worth your time.
PS: the music now playing screen on this one isnt crap!!!
