Ok, let's try this. I have NOT tested this as I have not seen the problem first-hand.

In ./includes/cron/arcadeupdate.php:

Find:

PHP Code:

 $DB_site->query("UPDATE " . TABLE_PREFIX . "games SET highscorerid=$value[userid],highscore=$value[score] WHERE shortname='$key'"); 


REPLACE with:

PHP Code:

 if ($value[userid]!="") {
$DB_site->query("UPDATE " . TABLE_PREFIX . "games SET highscorerid=$value[userid],highscore=$value[score] WHERE shortname='$key'");
} 


I hope this works for you. Let me know as I am curious now on your issue.
