Tascam - X1 issue

I recently picked up a Tascam US - 800 for $99 I normally use a M-Audio 24/94 PCI card, but for $99 I thought what the heck 6 inputs cool.

Okay the issue. I can see the unit in the audio setup page of X1, but it is grayed out. I can set it up in Reaper, Real Band, Multitrackstudio, and even cakes own MC5, but not in X1. SO i figure i am missing something.

Any ideas i might try to figure this thing out?

Oh i almost forgot, i have a dual core 2 gig of ram, XP pro sp 3 Sonar essentials C

Gotcha, that worked, and i was also missing the I/O  box on the tracks view, that helped. Thanks FFB, i appreciate the reminders.
