I have several maxisys elites with maxiflash J2534 boxes and I am unable to enter programming on BMW cars.  I can access diagnostics and hot functions just fine but the system will not go into programming.   I have used this exact hardware setup in the past to program BMW and it seems from some update I am no longer able to connect to the cars.  I have tried several of our tablets on several BMW's.

How do I fix this so I can connect to BMW?
