I can't seem to get it to work. I'll write a step by step incase I've missed something.

1. I downloaded the 3.3.5 player and the Vanilla Sounds
2. I extracted both in World of Warcraft 3.3.5a\Interface\AddOns
3. booting up the game, going to addon tab
4. The addon called "VoiceOver Data - vanilla" is marked red and it says "out of date"
   
5. I check load out of date addons
6. I go into the game.
7. There is a button on the mini map, I click it and I get the options panel for the addon
8. Everything looks ok.
9. I right click on a quest npc. Generic voiceline
10. I check the data moduels tab. Seems fine
    

Please help. I've never played WoW, because I'm dyslexic and I play games for story. I started as a blood elf hunter, if that is relevant.
