Upgrade question from 3.5.4

[mqqn]

Hi folks -

I have a vbulletin install that is running 3.5.4.

I am a co-admin, and the other admin, who is the person who started the forum, wanted to put on as many hacks as he could - so we have everything from games to user name changes, anonymous user, game arcade, vbcmps, the works.

Now I cannot get the upgrades to work - I have created test intances on another server and loaded the databases trying to upgrade to 3.8 until I am blue in the face, but no luck.

Once the upgrade completes, the vbulletin does not work, giving me many errors.

Does anyone know how I can just get the plain vanilla vbulletin data out of mysql and then load that - hoping to just wipe the slate clean of all hacks and add-ons so that I can upgrade clean and still keep all of my post history and user registration information etc.

Thank you in advance for your considered reply.

best regards -
