Create A Forum - Support Forums

So recently I found this awesome site called createaforum.com and thought, I would give it a try!
so normally nothing would've happened and never be here, but my server got hacked, and also hacked my forums and can't get in my administrate page anymore where I can edit my forums, and this hacker demoted me and changed the password of my forums, and can't access it anymore, any help/fix for this?
