Players try to log onto the server they get a message saying they don’t have the hak file . Not sure what hak they need. The Server is Aventia 4 Unlimited Levels .
EDIT - I gather from this post that you were the Aventia administrator in the past?
Only the Aventia server admins can know what haks are required, as the module istn’t published on the Vault.
You might try the Aventia forum.
