Servers: I think I did it wrong...

I created a dedicated server, and whenever I log on, this happens:

That’s bad. It stays there the entire time, and I can’t open anything, like the build menu (it pops up a new error that goes by pretty quickly).

What did I break/do wrong, and how can I fix it?

EDIT: Server was installed using Slayer’s Dedicated Server Installer v4, btw. http://www.facepunch.com/showthread.php?t=581128

Addons?

The problem was there the first time with no addons, but I’ve added Wiremod and PHX3.

Delete gamemodes/sandbox and base and update.

Hmm, that seems to have worked. Thanks dude.

Crap, I banned myself screwing around on my own server XD. That’s humiliating.
