"PRO-X is at the moment NOT compatible with D132! This is 100%
The problem is, that PRO-X was developed with an other company - D132 is 100% Stadlbauer (Carrera). They are at the moment in negotiations to solve the problem, but till now nothing is fixed, due of copyrights and licenses. Mr. Stadlbauer jn. promised to put all their energy in solving the problem, but at the moment there is no possibility to adaped PRO-X to D132."
Well there you have it....
