this might just be a bug with your game, but i'm using my files from the downgrade, since i have a patch 7 copy. it's a little bit annoying, but the german language/text files are still pretty much intact and working well.
be careful not to change files you do not own, otherwise you might break things! when you try to fix it, i suggest changing the radio to english first, and then change the language of the file you changed to german. after that, change the language of the file back to english and change the radio to german.
also, when you use the american radio hud/icon wtd, it's not backwards compatible with your original files. the american files have a button for you to make it backwards compatible, but you can't do that without reinstalling gta.
i suggest getting the files i made for this, or otherwise at least just giving the english version to the files you have already. if you want to give the german version to the files you have, then change the line that says "wtd" to "wtt".
i have been having problems with this mod as well. no matter what i do, my game boots up fine, but when it first boots up there is no music (all radio stations are off). i have tried downloading the.gxt files from other mods and renaming them with the mod name (e.g. "american.gxt"), but to no avail.
i'm having a problem with the radiohud and radio files. there's no radio stations at all in my game when i first play it, it's like the files never even made it to the game. it works fine if i restart the game but after restarting it doesn't work. i tried reloading the files but it didn't do anything. 3d9ccd7d82
