Authentication Error, Code: 4

I get an authentication error when trying to connect my last.fm account to mpdas.

Here's the output

(19:51:24) [ERROR] You are not root. Not changing user ..
(19:51:24) [INFO] Cannot parse config file (/home/USER/.mpdasrc).
(19:51:24) [INFO] Using Last.fm service URL
(19:51:24) [INFO] Connected to MPD.
(19:51:24) [ERROR] Code: 4
(19:51:24) [ERROR] Authentication failed. Please check your login data.
(19:51:24) [INFO] Closing mpdas.

And my config file

username = USERNAME
password = PASSWORD
runas = mpd
debug = 0

I've just recently changed my password to cut out any unnecessary special characters so I know both fields are valid.
