hey jimi
i can tell you this happens to me all the time. not only on multiplayer, but when i set traffic to max, and fsx tries to load many textures at the same time, it will turn all of them to the default main texture (the only Texture, not the texture.something) wich is the #1 blue angel in this case, but it happens with all the planes. i dont know what to do to fix it, but i would try to rename this folder and leave no Texture folder. of course, the textures that are common to all the planes (such as VC textures) are located in this folder, so I THINK you would have to copy em to all the other folders. well, im just guessing, trying to figure out a solution, but im not really sure if this works
OR you could just leave the texture folder there, and create a new one for the first texture (blue angel #1) with the specific textures only, but i dont know if everyone would have to do the same, or what
