To add to this, when True Blue was helping us with this issue last year, they found that although the 1.503 firmware did work, they could only get it to work with a single thermostat. It wouldn't work with multiple thermostats/modules in the same program, or even in different program slots.
I guess a separate RMC3 could be used for each thermostat... :-)

Just thought I'd update this thread, though not with any good news...
I have been communicating with Control Concepts, the CSP that built the module
that worked fine until Crestron/Trane screwed things up. They have been working
consistently to resolve this, but still have not had success.
Not sure that I understand how this can not be resolved or at least determined
to be a lost cause...
I will say that Victoria at CC has been fantastic with communications and
updates...
That said it looks like the only solution in the foreseeable future is to use
an RMC3 with v1.503 - so lame!...
