Can't request password due to new email address

I started a development Zen cart site over a year ago, and then later abandoned it, but left it up for reference purposes. Well, someone stumbled along and found it and purchased something, and I never knew! Now I'm merely trying to go back in and disable the purchase options, but its been so long ago I can't remember my password and my email address has changed. I've tried to change it directly in PHPMyAdmin, with no luck, I've tried the Drop Table - Rebuild Table solution with SQL query staements with no luck, and tried the replaced the admin info with the SQL Insert solution (restoring the Admin-admin) with no luck. My PHPMyAdmin gives me an error that says: Error. You must be trying to upload a file too large (when doing the drop table). When trying to directly change the values for either password or email I get PHPMyAdmin php errors like this:
Warning: Invalid argument supplied for foreach() in /usr/local/cpanel/base/3rdparty/phpMyAdmin/tbl_replace.php on line 142

Warning: Cannot modify header information - headers already sent by (output started at /usr/local/cpanel/base/3rdparty/phpMyAdmin/tbl_replace.php:142) in /usr/local/cpanel/base/3rdparty/phpMyAdmin/libraries/ob.lib.php on line 83
.... along with 5 other errors about header information.

So, I'm at a loss. Any suggestions would be appreciated.

phpMyAdmin - 2.11.9.1
MySQL client version: 4.1.22
unsure of Zen cart version

PHP version 4.4.4

Tutorials/FAQ link in the orange bar above - try reset admin password in the search

Thanks, but I've tried all of those that seemed to apply, and get the errors described in my post.

Any other ideas?

thanks.

Those are all symptoms/issues that you should direct to your hosting company, as it appears there's something amuck with your database and/or your phpMyAdmin, or worse. That's not a Zen Cart specific issue.

Sure enough! Contacted ISP and that version of PHPMyAdmin has an incompatibility with their web user interface. They gave me an alternate access to PHPMyAdmin and I was able to make the table changes I needed. Thanks all, for your help!
