Cross crash on load only with U46 plugged in

everytime I open Cross with the U46 plugged in the software crashes at the splash screen.

What I've done
uninstall/reinstall Cross and asio4all
verified sound card by loading DVS 7.4rc. it ran fine with cd time code @256ms latency
verified Cross by using a different sound card (m-audio fasttrak 1x1) with asio4all driver. the software worked fine and doesn't crash at launch.
deleted C:\username\application data\mixvivbes folder
tried opening with a new collection
all of these things failed so i'm stumped it's just strange that only the U46 would cause it to crash anything other setup and it's working fine.
