I'm getting this error when trying to install.

Database error in vBulletin 3.5.2:

Invalid SQL:
CREATE TABLE `inferno_attack` (
  `aid` int(11) NOT NULL auto_increment,
  `aname` text NOT NULL,
  `atype` text NOT NULL,
  `asprite` text NOT NULL,
  `amp_cost` int(15) NOT NULL default '0',
  PRIMARY KEY  (`aid`)
) ENGINE=MyISAM;;

MySQL Error  : Table 'inferno_attack' already exists
Error Number : 1050

I checked phpMyAdmin and all the tables do exist, the installation won't continue though.
