User 1 no longer appears to have admin access, help!

Hi,

I have a Drupal 6 site around 6 months old. A couple of hours ago the user 1 account had complete admin access and now it does not.

For example, when logged in as user 1 (the orginal admin user), I click on 'content management', and all I see is a comments link and no way of editing existing content. When logged in, and browsing content on the site, there is no edit link like their normally is. In the control panel, I can't see admin elements like where you add new modules.

It appears my user access is very basic and I can add content etc.

The two things that have happened since when it was working and now is that I installed the 'uc_attribute_stock_filter' module and my Apache server crashed. The server is now up and running.

I have emptied my cache and sessions tables to see if this helps and it hasn't. I can see there is an 'access' field in the USERS table in phpmyadmin, could this be changed to give user 1 full admin access again?

Any ideas why user 1 no longer has admin access?

Thanks for an help,

Joe
