Hello, some feedback:

$vbulletin->db->query_write("DROP TABLE " . TABLE_PREFIX . "mu_ignored_ips"); 
should be:
$vbulletin->db->query_write("DROP TABLE " . TABLE_PREFIX . "mu_alert_ignored_ips");

And
$vbulletin->db->query_write("ATLER TABLE " . TABLE_PREFIX . "user DROP `main_ip`");
should be:
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user DROP `main_ip`");

And
$vbulletin->db->query_wrtie("ALTER TABLE " . TABLE_PREFIX . "user DROP `num_alerts`");]]>
should be:
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user DROP `num_alerts`");]]>

) ENGINE=MyISAM DEFAULT CHARSET=latin1");

does not work for me, my server does not use MySam, it uses MySQL.
If I delete "ENGINE=MyISAM DEFAULT" in the product the tables are created but I get errors in Display Events:

Notice: Undefined index: charset in /home/mydominion/public_html/foro/includes/init.php on line 144

Notice: Undefined index: url in /home/mydominion/public_html/foro/includes/class_core.php on line 1991

Notice: Only variables should be assigned by reference in /home/mydominion/public_html/foro/includes/init.php on line 213

I hope this info helps.

Regards
