Reply to Odd LPD8 behavior

i've had an lpd8 for a while and a mixtrack with a dj io sound card today it's stopped sending midi from the lpd8 to all of my programs (trakor ableton massive) i can monitor a signal from midi monitor but can't get a input signal to to anything the output is there no input i believe that something in mac os is eating the signal??

also tried it in different ports

MBP 4.1
OSX 10.6.6
Traktor pro
lpd 8
mixtrack
dj io
