Okay, I managed to fix the writing issue - but now it won't work in game. It's definitely responding in TF2 - when I type in the hldj stuff it acknowledges it, but...
I hit "la", see my list of songs. Type 4 and hit enter to queue that up. Pressed my play key. Nothing.
Okay, bump because this is the third time over I've checked EVERYTHING it says in the sticky, and it still doesn't work. I fixed the writing problem, but now even when I select the file I want to play (la, then 3 because thats its number, it says it wrote a file), my play key doesn't work, nor does typing in playaudio manually. What gives?
