Can anyone explain my problem with the exterior lights? No lights at all and aircraft is divided in to two parts by white/red square. Parts of the fuselage are even flying above the aircraft. Problem starts immediately after selection of aircraft with fresh start. Graphic card GForce 9600 GT. Looking forward to any solution.

I think you run out of memory.Check your usage with gpu-z

Have a look at the picture I attached............

Update your drivers and try lower display settings

Even in the selection menu........

Is it just the ngx or is your scenery getting corrupted as well?

Just the NGX, no other product, for example the 747400 works perfect. Could it be an activation problem?

Just a shot in the dark, but I would suspect a file has been corrupted. Is it only with certain liveries?Edit: Also, has it looked fine before and you're only now experiencing it or has this happened since the install?

All liveries are corrupted from the point of installation. Maybe it could be a memory problem but the problem starts even in the selection menu. Squares seem to be made by corrupted beacon/strobe lights but parts of fuselage are on top of aircraft. Looks like texture problem I noticed with Level-D a/c, probably caused bij overheated/overloaded graphic card?
