Help L2OFF - All in one npc for High Five and L2comm issue

Greetings,

I have been searching for days but unable to find any AIO npc for L2off HF, i came across this one but sadly it is not usable in HF as server keep saying the AI has sayfloat (talked) error,

Can anyone help to port this great npc to HF? if you also find a working buffer for h5 could you share it as well?

The npc I found, but it is not compatible with HF

Also I am unable to get L2comm started as it keep asking serial key even I have already inputted the key, I had it started successfully on my first run, but the other day when I boot up my server it is not working anymore, can anyone help? Thanks
