Dp4 + Reason Rewired = Stuck Notes, Reason's sequencer stuck while looping Options

[Fields]

So I've got Reason rewired to a new aux track in DP4, sound is coming through, everything is good.

I have a couple measures in Reason's sequencer looped, when it comes up to the end of the loop the Reason sequencer stands still and plays stuck notes, meanwhile, DP4's counter is going along fine cycling through the loop over and over while Reason is stuck at the end of the loop.

I'm assuming this is a Rewire issue?

Reason 2.5
DP4.12
G5 Dual 2GHZ, 2G Ram, 250G HD

purchased both programs

Anyone have a similar issue? advice?

Thanks,
