[HELP] Alphabet Problem.

I have came across an alphabet letter error.

Whenever i would like to you the letter M it show black box instead of M.

All other letter work is just the Letter M,Z and maybe some others to.

I have tried editing the etcitemgrp.dat file and in id 6903 which looked like this: 2 6903 0 0 2 5 0 icon.etc_m_i00

But non of it seems to make the letter M and Z visible.

This is the code i use in htm: icon.etc_alphabet_m_i00

Can someone please help me fix this error?

Thanks in advance.
