I purchased FS2 PMDG747, did a clean install, patch, stick/key config and FS9 load. All worked functions worked normally during pre-flight until first checklist, button illuminated, main button/no response.Begin trouble shooting, config, uninstall, re-install, no joy.Re-download and repeat dance, feels a little like Falcon4 RP3........FS2 LDS767 works fine, PMDG 744/F current patches. Sony Vaio PCG-TR3A Laptop. Saitek ST290 Pro stick.Any suggestions?Regards,John S. Hayden

Hi John,FS2Crew was activated?You configured the Main Button as per the manual?Double check the Main Button. That's all I can suggest at this point.Perhaps try re-assigning it to a different joystick button or key.-Bryan
