Which one do you have:

First gen: http://medias.audiofanzine.com/image...ack-611274.jpg
MKII: http://medias.audiofanzine.com/image...ack-632220.jpg

If you select to trust M-Audio, I don't think it will prompt when you install the driver. I'm asuming you mean the pop up similar to this: http://www.davidegrayson.com/signing...n7_maestro.png

I'm not sure what the current fimrware is, and it will depend on which device you have. Also, I don't use Ableton, you might get better answers for that specific problem from their forum: https://forum.ableton.com/
