Has anyone seen this before? The only recent change to my system was the installation of Ultimate Terrain USA/Europe. Also, my cabin lights stopped working for some reason. This is the FS9 version.

It's also doing this all of a sudden. This occurred shortly after climb thrust engages. The FMS was controlling the Speed and profile then the speeds disappear off of the tape and it goes into low speed protection and then what you see on the screen shot. The wing flex problem above happens intermittently and this one happens consistently. I really do not want to reinstall as it takes forever to get all of the liveries back in there. -I have ran the installer repair-reinstalled both the x86 and x64 C++ Libraries (running W7 64 bit)-ran a registry cleaner-Ran the Flight 1 repair toolThe aircraft was working fine the last time I used it 2 days ago.

Hiya Dan, This may sound crazy, but in the first pic and issue with the cabin lights, were you using my Guinness livery by chance? Only reason I ask is that I have had my concerns about the way FS would use the Alpha channels and maybe take away from the the max number of lights or for whatever reason conflict. I have had times where my cabin lights didn't work also, but to the best of my recollection, it was only with my GNS paint. It could also be that I just never noticed in any others, but have to go with what I saw.

I wasn't using the guinness livery in that one I upgraded to W7 since then and haven't installed it yet. That was the PMDG Virgin Atlantic livery.

I think I might do a reinstall since I just completed a flight with the PMDG 747 with no issues. If I save all the textures folders and the aircraft.cfg for the liveries and then copy them back in after a re-install will that cause any issues. I'm just trying to avoid installing all liveries again with the installers as it takes forever.

I've done it without issue with FSX, so don't see why you couldn't. I normally do my whole Aircraft folder (Since I have a lot of customs and light edits etc...). The only issue is you won't have uninstall options in control panel, but that is more of a bonus than an issue.
