Hi Sanal.

A lot of people had that issue of the flashing graphics/textures in v1.1, just having the VC only and NOT the VC+Passenger Cabin, which is the default after installing, got rid of the flashing graphics. See THIS TOPIC. I have done some tweaking since then, and now I don't get the flashing graphics/textures and I have the passenger cabin too.

To get your engines started, try my method HERE AND see if that helps.
