Using role-scoper 1.0.4, I can no longer access the Roles > Options page. It says "You do not have sufficient permissions to access this page."

At some point I replaced the default admin user with one with a cryptic name (that is, I made a new admin and deleted the default one), as recommended for site security. I guess it is this that is causing the problem.

The problem goes away if I upgrade the plugin, but as I can't then get at any of my downloads (see previous post), I'm stuck.

Is there somewhere I can change the name 'admin' or whatever to my cryptic username in order to use options again, if I can't get the latest version working?
