Reply to vci 100 se mapping problem

Hi, I'm new to the vci 100 se.

I have it up and running and it seems fine apart from when I import the dj tech tools mappings, I then close the preferences pane open it back up and it has reverted back to traktor pro default mappins. Is this normal and is there a way to save the mappings ?

i'm on a mac book pro

many thanks
