There is a simple explainable reason why deuce's cannot change their name: They are looking at the wrong folder.

In windows 7/vista, the majority go to start > programs > ace of spades, the files are there but it is missing the kv6 and png folders. After you try to edit the config file, your name does not change. This is because it isn't the right folder.

In fact, the folder is in: C:// > program FILES > ace of spades.

I hope this helps people.
