Newly Dowloaded Instruments Will Not Trigger

natives

I recently downloaded new instruments and they are in my library and when I click them to hear the sample track they play and when I hit the single note in pad mode on Maschine the one single note triggers. But when I put the Maschine in keyboard mode no sounds trigger. I dont have this problem with any of the original instruments which I downloaded initially upon purchase of Maschine. They all play in keyboard mode. The names of the new instuments show up on the Maschine screen and also show on my computer screen in Msschine2 but they wont trigger when I hit the pads. What could cause this? Thanks— It just randomly started working. I didnt do anything. Maybe it was completely downloaded?
