Im running Prosim using their 737-800 with all modules. Under the Prosim 737 MCP, sometimes I can see lights on but nothing is on on the MCP737-R. Or lights flash on then go off. If I open the VAInterface, I have to constantly reselect the ProSim 737 and resave to get things to respond. And it seems to be a hit or miss with the CMD light coming on and showing up on my MIP. Any ideas, maybe reinstalling the VAinterface? Im running current version, and also FSUIPC is checked for the ProSim MCP.
