ok i found a way to get past the linkdead error, but the only problem is, its for the linksys router only.

Heres what i did: i went to the linksys website, downloaded the latest firmware i could find. Installed it, then went into my router config, changed it to get ip automaticaly. went into forwarding, made the first line(where it asks for the ports) i put 0~13331, then click tcp and udp set it to my ip on the router, clicked enable, then went and tried to play the game again. this time i made a character and go into the world. everything works fine. hope this helps anyone with a linksys router.
