bought everything and it worked great. rebuilt my laptop and now SD2 doesnt receive midi from the yamaha dtx502 module. what am i missing? windows 8 64 bit with SD 2.3.1 / installed the latest toontrack Solo (64 bit) / installed yamaha driver / installed MidiOX and verified that it is receiving midi from the dtx502 module. clicked on mapping and selected the e drums preset. / Selected the dtx502 as the midi device in Solo. / hit the pads and the drums on SD dont flash. any ideas?
