Looking at the install code in the product xml file, I found the following additions are made to the user table (assuming you had the latest version installed):

$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_ban tinyint(1) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD times_played int(11) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD is_arcade_mod TINYINT( 1 ) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD fav_games TEXT NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD user_sort VARCHAR( 15 ) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD user_order VARCHAR( 4 ) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD user_g_pp MEDIUMINT( 8 ) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD user_s_pp MEDIUMINT( 8 ) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD def_g_cat MEDIUMINT( 8 ) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD game_skin TINYINT( 1 ) DEFAULT '0' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_mod_privs TEXT NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_pmactive tinyint(1) DEFAULT '1' NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD games_played int(11) NOT NULL default '0'");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD time_played int(11) NOT NULL default '0'");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_points int(11) NOT NULL default '500', ADD arcade_spent int(11) NOT NULL default '0', ADD arcade_won int(11) NOT NULL default '0', ADD arcade_high int(11) NOT NULL default '0'");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD create_tourney tinyint(1) NOT NULL default '1'");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_sess_gid MEDIUMINT(8) NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_sess_start INT(11) NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_gtype INT(11) NOT NULL");
$vbulletin->db->query_write("ALTER TABLE " . TABLE_PREFIX . "user ADD arcade_session MEDIUMINT(8) NOT NULL");

so you could probably either find a way to execute that or else you could edit it into SQL queries pretty easily. Obviously all the data in those fields is gone.

I don't know whether or not that will fix everything, but it may be worth a shot.
