Hey hey, I have some updates
Yesterday I tried a bunch of things;
1: I tried running ETS2 and TMP in admin in admin and radio did not work
2: I tried using the music player feature in both ETS2 and TMP and it did work.
3: I tried validating game files, did nothing.
But I found a solution on listening to radio with my friends; just listen on radiotrucker.com
Thanks for the help but I don't think I'll get the in-game radio to work.
