You are absolutely dead on. That was the problem. I had custom scaling, changed it back to 100 and tried it and it worked. Thank you so much

Thanks for the reply. The problem is I don't have that green add button in my PMDG ops center.

P3d v4. I download a livery of AVSIM, said compatible with P3D. I open the PTP file and it just opens ops center and nothing happens. If I go to the OPS center and click tools, execute PTP I get "this is for 737-800 WL but the variant is not installed".......but I have it installed.....What gives? I've tried running it as admin and everything.

That was the problem. Thanks

Sounds good. I just reset my motherboard defaults, replaced my CMOS battery and changed the BIOS clock to the current time. I will let you know what happens. Thanks

I reset my bios to default and it's still doing it. Now that you mention it, My CMOS battery I think is dying. My PC can never keep the time and I always have to update it......that affects the plane?

Yeah my CPU is overclocked.....should I try bringing it back to stock?

Thanks, I'll edit that. Yeah everything was fine. It happened twice. Once I was cruising just fine at FL380 .83 mach and the other time it happened as soon as I rotated on take off. I'm using FSX stock weather. The winds aloft are a pain but I don't think that's the cause.

out of nowhere randomly I notice i'm drifting off course and when i try to press the heading bug, nothing happens then the plane starts violently flipping in the air all over the place and there goes my hours and hours of planning. It's really frustrating. Any help or ideas?
