Are you using shaders? This happens to me when shaders are on (though I don't play ingame anymore). I think you may have to download the most recent drivers for your graphics card.
well then re download your character
type /dl lordmax155
happens to me all the time
its just that your item.dat/equipment.dat file shows that you have a head texture, but you custom folder doesnt have the picture for it
That happened to me a while ago, too.
Try deleting your custom folder (toribash 3.88»custom»lordmax115)
Then /dl /lp your tori in game again, it works for me.
