Hi, I just installed P3D and wanted to install the PMDG 737 800/900 and 600/700, then I installed the FS2Crew, but when I start the sim and press the PWR button on the FS2Crew Panel, I get an SDK error. Then, I press again and it starts working, until I have to start engines, when the FO says that A/C is not configured. I just burned all the options. I downloaded the last versions. I just don't know what else to do. If any ideas, they're welcome!
