you want to edit p def from armor that armor says on game (in item description) or the stat that armor gives in game.

HappyViolence, was not moderator for more than 2 months (if i am not wrong), so he gets demote to membergroup that he had before the promote.
This is not high five if i am not wrong because high five got one DB. On freya, there 2 databases. Login database and game database are splitted to L2gjs and l2jls.
However, this is not problem from your server. This is client problem (that you cant login to your server). Try to download another system(i recommend freya one) and add on l2.ini serverAddr=127.0.0.1
That's true, hellbound is abandoned :P
However, i remember L2J Hellbound servers, that were da best....For me best of them was
