Co-Admin up his own bum

[Sharkyman]

I am the site owner of my forum but when it started to get really busy I made someone whom I thought I could trust co admin. Now, while I was in hospital having an operation (with no internet connection) he has de-admined my account and contacted the hosts, forged my signature and transfered everything over to him. I am in discussion with the hosts to get all the passwords changed for the access (ftp etc) which should be done today.

Question is...how can I make myself admin again with just server access? He's refusing to do it via the ACP but I need to do it so I can knock him off his perch, as I pay for the hosting and the vbulletin licence and am in the process of getting everything changed back with the hosts but I don't want to have to start from scratch as I have 100K+ posts and a few 1000 threads but need to become admin again.

Am I going to have to go into the database?
