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

Database error in vBulletin 3.0.7:

mysql error: Table 'gamechallenges' already exists

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

Wrong forum, mate. This is for RPG Integration Hack.
