I haven't seen a working Argus in a long time. FFXI app required connecting or logging into a server. SE threatened legal action on the creator so he took down the server.
I think I've looked at Argus before to see if I could just update the offsets, but it's either not possible or it uses some strange offsets that I can't really reverse engineer. I'm pretty sure if you could change the offsets yourself and they were the normal npc/mob offsets, wiccaan's or apnea's offset finders would have fixed them a long time ago.
