Recording Midi freezes up PT... WHY... *HELP*

[toomuch]

Ok so Im running Mbox LE with the latest update.. I use the oxygen 8 midi controller and also use the m-audio midisport 2x2.. Im using a roland a-37 contorller that is triggering my motif and recording the midi info into protools.. through my midisport 2x2 In a goes to mt a-37, with the usb button enabled while recording I can hear the sounds from the motif with that cabel (out a) running into the motiff (in) so it crashes and other than the normal buffer playback problems, when I record midi it locks up on me and I have to close the whole program and restart.. THAT GETS ANNOYING.. so am I configuring something wrong here.. Im about to give up and just buy Logic since all my roommates rave about how great it is anyways..
