i downloaded a texture that is supposed to be installed in the PMDG 747-400. the directions were to add the texture in the aqircraft cfg file. so i went to the last texture and added the info as the next texture. when i tried to close the cfg file it asked if i wanted to save the changes to the aircraft file (thats the name of the ac config file) and when i say yes it says access denied. all my other textures from PMDG installed in the aircraft cfg file but when i typed this in it would not save it. i checked to see if i had left anything out but thats not the case. by the way it was a delta texture and to think delta is the second largest airline in the world and PMDG didn't provide a livery for delta. i guess they are really in touch with (virtual) reality. any help is appreciated........thanks henry
