kazaa and morpheus use different formats for partial downloads, so you will have to use k-lite to complete them.
morpheus piggybacks on mldonkey to access the kazaa lite network
so you might need to have working nodes in your \mldonkey\fasttrack.ini file
that should bootstrap you onto the K-Lite network (unless you have firewall/router issues)
(* Known ultrapeers *)
ultrapeers = [
BTW xolox is an ad-free version of morpheus
but they both suck IMNSHO
but hey, to each his own.
