Also, the graphics settings work like this in terms of what's going on your tori.
Minimum - Shows head texture, joint colors and ghost only.
Low - Shows all body textures other than joint textures and all flames. (Doesn't show your hair)
So, just switch your graphics options to low and it should show your flame.
If you have hair and you want that to show, switch to Maximum graphics (it might be laggy though)
If that doesn't help, try typing /dl Mike60LeGacyX in the game, then when it says download complete, type /lp 0 Mike60LeGacyX.
Obviously if you type this before and it doesn't show, try switch your graphics settings, and if it shows once you type this, then that's all you needed to do..
