Dll, No Audio, etc.... 

OK! I deleated the track I had recorded (because I don't know for sure there was audio or not)and am starting fresh with the cockoswiki tutorials. I opened a new project, inserted a track.....and bam! When trying to select and input(mono or stereo) my only option are "not connected" one or two! I'm only trying to record guitar but if I choose midi the system sees my Audiobox. I feel like this is simple, but I'm moron....:)
