Database problems :(

[Malacia]

I was installing vbArcade, and ran the install file before i had edited the nessacery files, so i tried to go back on myself and change the changes made to the database. I tried editing the datastore table the row called usergroupcache , but i messed it up now the forums wont allow anyone on because of a permissions error saying you don't have permission.

The error message i am getting is :

vBulletin Message You are not logged in or you do not have permission to access this page. This could be due to one of several reasons:

1. You are not logged in. Fill in the form at the bottom of this page and try again.
2. You may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
3. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

And i get basically the same when trying to use my admin account.

(Please note, this is nothing to do with vbarcade, it's a database issue that was caused by my stupidity.)
