mysqld won't start after trying to reset password

[Matt Zumwalt]

After installing mysql and setting a root password, I stopped being able to log in to the mysql server. In an attempt to start over, I followed the Reference Manual's instructions for resetting the password (http://dev.mysql.com/doc/mysql/en/resetting-permissions.html). Basically, I located the .pid file containing the mysql server's process id and killed the process using the path for that file. Now mysqld won't start at all. Here's a transcript of what happens when I try to use mysqld_safe:

[wangmo:~] matt% sudo /usr/local/mysql/bin/mysqld_safe
Password:
Starting mysqld daemon with databases from /usr/local/mysql/data
STOPPING server from pid file /usr/local/mysql/data/wangmo.pid
050530 19:46:04 mysqld ended

Any thoughts?

I'm running mySQL 4.1.12 on Mac OS 10.3.9

Cheers,
