Errors when exec. World .exe

[LiquidRaven]

My world exe does come up but it gives me a shit load of errors like
Failed to connect to database: Access denied for user, using password yes and some errors like
erroe: error in getitems query and crap like that

also when i try the alternative

And if that does not help. Open mysql.exe ( found in c:\mysql\bin )
Type in: GRANT ALL PRIVILEGES ON *.* to '%'@localhost IDENTIFIED BY '%'; (press enter)
Close out of mysql.exe

it wont work, says enter password : no
