Help with ElevenRack in Pro tools

[JonWillford]

Hello,

I just received Pro tools 8 and an Eleven Rack and few days ago. I have pro tools running and eleven rack connected to my computer and the eleven rack window is showing in pro tools. So I create a new stereo audio track but when I go to the input selector on the track and try to select ElevenRig L/R I get a message saying "The input path could not be made active because the input path is currently not available. "

A few days ago I tried the same thing and it worked fine, but now I can't get it to work . Can someone help me?

Thank you
