invalid dds signature is ??and can I fix it?Thanks:-wavePete

Pete,Forgive me for asking the obvious, but when you extracted the Orbiter zip file did you tell it to "use folder names"? That log file looks like it can't find any of the textures. Mike

Yes, got the sub folders config,doc,html,meshes,modules,scenarios,textures and textures2.(using latest version of orbiter 2005).:-wavePete

Oh well. So much for it being something simple. x( Maybe someone on the Orbiter Forum can help.http://orbit.m6.net/v2/boardtalk.aspMike
