Hi, I'm Doing The Tutorial RKSI To RJAA. When Plane Loads Up everything fine but when i go on add-on-PMDG-options and load my fuel 1/3 full i click apply and then ok then everything goes black you can just see the cursur thats it, but still sound.please help.

You mean the whole screen goes black or just the CRTs?If it's just the CRTs, you probably have a license issue with your PMDG 747.It can be fixed by re-installing the PMDG 747 aircraft.If it's the whole screen, I'd update your video drivers (don't use beta ones, only WHQL's) and re-install the 747.Cheers,Bryan
