Pro tools LE Reason 4 rewire problems

[Trenchfoot]

hi, i posted this in the digidesign section but then realized this was probably a more appropriate section. so i apologise before hand for re-posting here as i know im not really meant to do it but im really stuck!

I use Pro Tools LE 7.1 on an intel mac with an Mbox 1 as the interface. i recently got a copy of Reason 4. When i use reason by itself i get sound throguh my Mbox to my speakers, when i use pro tools it works fine too. the only problem is when i have reason rewired throguh pro tools im not getting any sound at all. can anyone help??

How is it set up? If you're properly setting up the Aux and MIDI tracks there should be no problem.
