Unfortunately, I can't help as I am having a similar issue. I authorized Balance to be my ignition key on my desktop in my studio but I want to also produce when I am out and about so I am trying to authorize it also on my Red USB ignition key thing I got in my Reason box. Every time I try, it either doesn't register my ignition key at all or it say "fetching information" with a little spinning loading logo but nothing happens! This whole ignition key thing is frustrating!
Have you had any luck solving your issue? Also, can you have an ignition key authorized on Balance & the USB stick at the same time so it's less hassle?
