Cannot continue without a datbase connection

[Castle2.0]

Vsab, thank you for your reponse! Just to come the details.

<tcp ip="127.0.0.1" port="9000" telnet="disable"/>

...

	<database>
		<host>127.0.0.1</host>
		<port>3306</port>
		<username>eq</username>
		<password>eq</password>
		<db>eq</db>
	</database>

...

	<qsdatabase>
		<host>127.0.0.1</host>
		<port>3306</port>
		<username>eq</username>
		<password>eq</password>
		<db>eq</db>
	</qsdatabase>

Would I change all these instances of 127.0.0.1 to localhost?

Update: I can get all the boxes to pop up for all the main .exe, but I couldn't see it on the server select. That's why I just ran world.exe as requested and I get that message. Even with localhost in those spots I get the same message.
