Well you may be hosed.
Even upgrading will not help if files are corrupted or deleted
First thing is find the member directory. There is a file for each member. Plus a couple of other files for member count etc.
Each member file holds all the info such as username, password, User rights.
All the files are visible using a text editor nothing is encrypted.
I can't remember what line in the file is for administrator but it is near the top 10 lines or so. and it will contain the word administrator
If you have a backup try uploading your member 1 file.
It should be something like 0001.cgi.
That should be you. If that works you may need to upload all the member files.
Either you have been hacked or all of your files are corrupted.

It might also be helpful if you posted the url to your board.
So some of us can take a peek.
