I messed up my forum by renaming the folder

[doc fluty]

I had this stupid idea that if i renamed the folder i had installed vbulletin in.. and at the same time updated in my control panel.. everything would be fine. Now nothing works and i dont know how to fix it.. i cant log back in to change nothing... what can i do!?!?!!?

I can rename the folder back.. but when i go to log in as the admin.. it still want it to go to the military-forum address...

I shoulda left it alone

nevermind the problem.. I fixed it.

the original site is at www.bootcamp4me.com/militaryforum/forum.php

I tried to change it to... www.bootcamp4me.com/military-forum/forum.php

whats the best way to do this? without losing posts or anything made already (ie without reinstalling)
