OK, get rid of listen=0 for a start. Try this:

server=1
daemon=1
rpcuser= [YOUR_USERNAME]
rpcpassword= [YOUR_PASSWORD]
rpcallowip=127.0.0.1
maxconnections=12

Also, don't use special characters in your password or user name & ensure your wallet is fully synced.

Edit: If it still won't connect, type:

bitcoind getinfo

& post the result
