Do I really need to spell everything out for yous?
1. You need a 6 moths old forum account with at least 25 posts to play aO.
2. The dwkey.dat, keys on the site and the parameters are only found in the tutorial on how to set up a server. Maybe because they are only needed for setting up a server?
3. The files posted in this thread are useless as you'd need an account to play. And if you got that you've probably downloaded the files already..
4. The reason you can't visit the linked 'DLC page' is because it's in the trash can. It's just linking to MPGH anyways.
5. DON'T SPAM TO GET YOUR 25 POSTS, YOU WILL BE BANNED!
Thats kinda what I figured.
So if you want to play aO, you need to have a 6month old account, and 25 posts with it. End of story.
