Hi guys, I have a Problem with my favorite add-on for the FSX. I have a new Macbook Pro with quad core i7 2,4 ghz, turboboost up to 3,2 ghz and a Nvidia Geforce GT 705M inside. I installed Win 7 Home Premium 64 bit via bootcamp, did all the updates and installed FSX with Acceleration pack, thereafter the PMDG 737 NGX and the PMDG 777. As I tried to activate the 777, it won't work and an error occurred because I forgot to deinstall the 777 on my old notebook and my license was in use, eventhough I was able to load a flight with the 777, but it was completely cold and dark, no PMDG initialization started, the landing gear was retracted, the yoke was tilted to the left and I wasn't able to click any knob. So I deinstalled the 777 on my old computer and activated it on the macbook, but nothing changed. Then I thought it is an installation error and reinstalled it, but nothing changed. The 737 works fine, but the livery manager crashes always if I try to install a livery, maybe you can also help me with that. I think I need to delete every little part of the 777 installation even the registry entries and then install it again, but where can I find it and do I have to worry about my system if I delete or change these files? Please help me. Hansemax P.S. Sorry for my english, I'm not a native speaker.
