The forum doesn't exist

[croller]

i`ve crerated the forum 2 days ago, and i`ve created 2 categoryes and some posts. one hour ago i have changed some of my smylies and now i can`t connect to the forum, and i recieve this:
The forum themethod.roflforum.net doesn't exist.

Verify the internet address you typed : themethod.roflforum.net,
and try again if there is a mistake.

It is possible that the administrator has chosen to delete it.

nobody has deleted the forum because i`m the only one admin. please tell me how to solve this
thanks
