Can't add/remove inputs in song setup

First of all, forgive me if this is a stupid question. I'm new to this.

A while ago i got an M-audio profire 2626 for recording and stuff. Everething went fine until my pc crashed, and I had to change to another one.

So i found another computer, and installed drivers and software etc. but now when i start Studio One, i cant add/remove inputs in the song setup. The Add/Remove buttons just aren't there...

Any help would be greatly appreciated

Just a shot in the dark....I'm a novice, too...
But under the audio device tab, what do you have selected (Selected in the pic). Also, when you go under the External Device tab (arrow pointed to it in pic), does your keyboard show up?
