I have ProTools LE and an MBox. The application launches and I can open/create sessions, but I get no input or playback. I can however hear mic input through the MBox.

Try quitting Pro Tools, un-plug and re-plug both sides of the USB cable (connecting MBox to computer), then launch ProTools and try again. In some cases this fixes the problem.
