Reason Rewire MIDI volume fader stuck

[grateful]

Hello,

I hope someone can help here. The situation is:

When I run Reason 3.0 as a rewire into PT LE 7.3 (mbox), the MIDI volume fader on the tracks will always slide back up to 127 no matter where I try to move it.

I called Line 6 who represents propellerhead (manufacturer of Reason software) and they said the problem is in Protools not Reason.

Otherwise everything works fine on this computer.

Does anyone here know how to fix this?

Thanks,
Grateful
