Missing Inputs

[magno]

I'm trying to record the mixer inputs in Cubase SX3.
I.m using a Delta 66 interface.
I used to be able to do this by setting up a track and recording the mon/mix inputs.
Basically I want to bounce some tracks down to a stereo track.
But now for some reason i can't assign the mixer ins to a bus.
The mixer ins are visible in the VST input section but not available as a device port in the VST connections/Inputs.
I've recently reinstalled older drivers thinking it was the new delta drivers limiting me, but no luck.
I do seem to remember inputs being labeled differently before.
I know I've screwed up something somewhere.
What have I done wrong?

Well it's been a couple of weeks of trying to figure this out on my own.
Within 5 minutes of posting here I figured it out.
The device port was assigned to an external instrument I had setup.
Deleted the instrument, and trust me I kicked the snot out of it on the way.
And voila! my mixer ins are back.
Thanks guys I think stopping by smartened me up some.
Hopefooly this may help out somebody in the future.
