I just installed the QW757. It worked just fine when I opened the sim, just black gauges. So I installed the service pack next. After that is when p3d stopped working. Now when I try to open it a loading bar shows up but then it just goes into the background. My attempt at fixing this was to uninstall all my Quality Wings files. I have searched all the forums and non of the solutions work on mine. I would prefer not to have to do a clean install of p3d. Any help would be greatly appreciated!!! Solution: Removed p3d file from %appdata%, %localappdata%, and %programdata%. Do not delete these files just incase this solution doesn't work! This makes the sim regenerate certain files.
