Ever since I set up this A49 Keyboard I haven't been able to get it out of "MIDI Mode" and the only buttons that work are the arrows underneath the OLED screen allowing me to change between 1 of 4 "Template (1-4)" modes. When I'm using the NI plugins it does not control the parameters of my selected instrument and none of the buttons that control the DAW (I'm using Ableton) are lighting up or doing anything. I've tried pushing Shift+PLUG-IN/MIDI and it does nothing. I've made the necessary adjustments in the Ableton settings under Link, Tempo and MIDI. I'm not sure what else to do. One thing I think might be messing this whole thing up is that in the NI software, it is still showing a serial number for an A49 I owned before I moved. I have a completely new setup now, including a different computer but I am using the same NI account I had before. I've entered in the new serial number but I can't see how to get rid of the old one and have the new serial as my primary device. I also didn't get access to my free instruments or even a trial with this new A49, maybe I'm not eligible to have that again, I renewed my 360 subscription and would love to get this keyboard working the way it's supposed to. Please help.
