i dont think you delete things in regedit
because i have not had to
if doing what i have suggested does not work then get in touch with patchou but it should work
oh and for people who want to multi colour there names this is how to do
[c=*]......[/c][c=*].....[/c]
you can put as many different colours as you want in a name
*the numbers code that you want the text to be
[/c] = end of colour
