I try to install the hack arcade in my forum but she gives me this error...

Database error in vBulletin 3.0.7:
Invalid SQL:
CREATE TABLE gamechallenges (
challengeid int(10) unsigned NOT NULL auto_increment,
type tinyint(1) unsigned NOT NULL default '0',
challengerid int(10) unsigned NOT NULL default '0',

PRIMARY KEY (challengeid)
) TYPE=MyISAM

mysql error: Table 'gamechallenges' already exists
mysql error number: 1050

I have installed the same version of the forum 3.0.6 in the same servant with another database but without the translation to the Spanish one and she doesn't give me problems the arcade.

In the official forum with translation in Spanish gives me the error that I comment
