Protools LE 6.4 and Reason Problems Please Help.. Going Insane Here

I have reason 3.0 and protools 6.4.. I am using the rewire plugin on a track and get sound from the reason rack.. As soon as I get ready to record and activate the record button on the track the track immediately mutes the sound and will not record the audio.. Anyone have any ideas using Reason 3.0 and MBox with Protools Le 6.4 -- thanks so much for your help..

check the piano roll screen, when you open that up theres a list of devices that you select, select the device where your recording from and highlight the little record button, then try again? this might be your issue. though i dont have much experience with pro tools.. yet. trying to get an M box soon haha, but i got other problems i gotta deal with now :/ with reason 3.0
