Smartbar2 issue!!

So we have 2 (6 channel with stage pins) smartbar2's in our church. 

they were working awesome, no prob for 4 years. We just did a remodel and now one of them will not dim if there is anything else daisy chained out of it....

It dims fine if it is the last in the chain but not if its in the middle....

Any ideas?

Thanks,
