Help! Cant install v3 arcade because of error adding db

[mrblah]

I had v3 arcade installed previously, but I screwed up something with the phrases I think which severely messed up something with me staying logged in the cp so I deleted all the files and things I created. I did not delete the mysql stuff it created since I dont know how or if its possible.

Well now I would like to install it again but I cant because of the old arcade db's Im assuming.

this is the error

Database error in vBulletin 3.0.3:

Invalid SQL: 
		CREATE TABLE vb3_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',
		challengedid int(10) unsigned NOT NULL default '0',
		game varchar(30) NOT NULL default '',
		status tinyint(1) unsigned NOT NULL default '0',
		datestamp int(13) unsigned NOT NULL default '0',
		challengersession int(20) unsigned NOT NULL default '0',
		challengedsession int(20) unsigned NOT NULL default '0',
		PRIMARY KEY  (challengeid)
		) TYPE=MyISAM
	
mysql error: Table 'vb3_gamechallenges' already exists

mysql error number: 1050

This happens during the install_arcade.php process after adding the templates.

So anyone know how I can get passed this?

[edit]
nevermind I see that it doesnt matter, I was on the wrong skin and kept getting a blank page when viewing the arcade since I didnt install the templates for that one yet (I had a hunch I didnt need to recreate the db's, but the blank page made me think something was screwed up). So I switched to the main skin and the arcade is fully functional.
