Since I see a lot of people having issues, i'll upload a tutorial.
1. Open your Ace of Spades folder, usually in C:\Ace of Spades
2. Open up config with Notepad
3. Change your name, the default name is usually Deuce, but you can change that, I already changed my name to Nyan
4. Done
If you have the access denied error, you could delete config, and make a new text folder.
After you created the new text file, paste this into it and change the name :
Fuck... tried to rush for first. Wasted like 3 minutes uploading screenies!
Edit: FUCK DUDE THERE'S AT MOST 3 SECONDS IN BETWEEN... FUUUUUUUUUUUUUUUUUUUUUUUUU
@Nyan An easier way of doing this instead of navigating to the C: directory is to simply go to: Start >> All Programs >> Ace of Spades >> Configuration
