[SOLVED] Please help! Manager lockout

Please help! I’ve messed something with my main Manager user’s group, so now I can’t login - I have the "Access denied" message! Please tell me how to revert it back through MySQL, or how to create a completely new Manager user from MySQL only?

Using MODx Revo 2.1.0 RC4

UPD: seems that I solved the problem by setting in modx_member_groups the following settings:
id=>1, user_group=>1, member=>1, role=>2, rank=>0
My problem was that I wasn’t relogging in, so MODx used the old settings without reloading the new ones.
