Like I said, I don't know where this "database" thing is located.. is it in my server folder?
you can do it two ways
First One .::. Before use you MySQL.sql in your PhpMyAdmin you search this is your SQL
at line 112
INSERT INTO `players` VALUES (1, 'Account Manager', 0, 1, 1, 1, 0, 150, 150, 0, 0, 0, 0, 0, 110, 0, 0, 0, 0, 0, 0, 0,
50, 50, 7, '', 400, 0, 0, 0, 0, 0, 0, 0, '', 0, 0, 0, 201660000, 0, 100, 100, 100, 100, 100, 0, 0, 0, 0, 0, '');
you see things wrote in red
this is posx - posy - posz
change it before you get your sql in PHPAdmin
\\\\\\\\\\\\\\\
\\ Other Way \\
\\\\\\\\\\\\\\\
go to PhpMyAdmin where is you make user and database
go to accounts
you will find account manager ....
press edit and search for posx- posy - posz
