Help with the game.

I have no idea how to install it lol.
Okay so I have the 4.0 NCsoft game installed on Cprogram Files, then I downloaded the gamez aion launcher from the homepage and installed it, entered the game then it sayed the no server error.
Then I saw I need to downgrade, so I downloaded all this .rar files I extracted them but I got a couple of errors like "corrupt file" so I guess they haven't been extracted to the fullest. So what is the next step? Copy them anyways or try to download them again?

 

1 more question about the servers. I don't get how this stigma is.
So On Siel I get all skills, but there are no stigma skill at all, on Lumiel I can get stigma skills but there are no skill at all? So wich server is better for pvp then?

 

Mhm. What program are you using to extract the files?

Are you sure you let them all finish downloading before trying to extract?

EDIT:

Siel doesn't have a stigma system. Meaning, you get all the skills there are.

Lumiel has a stigma system and you will have to build a 'stigma tree' wisely, choosing the skills you need the most. You don't have all the skills there.

 

I'm using winrar. I'm just trying to download them again with avast turned off.

EDIT: Downloaded again without problems if I turned avast off. Let's see how it's working.
