Ok, I really need somebody's help!

Above is an error I'm receiving and I can't access my forum at all. I tried to do a cleanup using Impex as I'd already done a test import from an old forum, and wanted to now perform a full import. Unfortunately it seems to have messed something up entirely in the process.

I have no idea what any of that means, but I know some nice soul here will!! I don't have any data on the forum that I really need, apart from a style I've spent a week creating. It wasn't backed up and I'd amassed quite a lengthy additional.css file! Really annoyed at myself for not backing it up.

Thanks in advance!

Somehow just after posting the above message, and without me doing anything, my forum is back in action. HOWEVER, I seem to have wiped my admin user account.

Any ideas??

Ok, even funnier. I managed to reset my password using the forgotten password tool and now I have this message.

Date the ban will be lifted: Never

LOL. Something has gone seriously wrong with my forum!

Ok, so I seem to have solved my own problem.

I uploaded tools.php from the do not upload folder that you get when you download bulletin to the admincp folder as well as the install folder back to my root, and navigated to tools.php it in my browser.

I then reset the admin privileges for my user account and everything is working again.

I thought I'd post the solution in case anybody else runs into this problem.
