The map hasn't updated recently, so if the door textures are missing here, they're probably also missing in other maps. Try disabling other recently updated/installed addons or verifying GMod's cache.

i downloaded alot of mods and i want them ALL and i dont want to delete them

Sorry, I don't know what else to tell you. Are the door textures also missing in other maps? If that's the case, either your game files are corrupt or you have a faulty addon. There's nothing I can do about that.

You don't need to delete any of your addons; you can temporarily disable them in the addons menu (you may need to restart the game afterwards, though). If you've pinpointed the one that's causing the issue, you can let its creator know and hopefully they'll fix it.
