Ok, your last userid in the computers range.

If your userid is higher than 50.000 do the following things:
open lc_global.php and search for:

$minkiid =  500000;
$maxkiid = 1000000;

and in londonchase_admin.php for:

$maxkiid =  500000;

Mister Y lies in the range of 50.000 - 99.999
over 100.000 are the userids for all players they play a double game (2 player game).

so, you can change minkiid into 100000 and maxkiid into 120000.

I think that will help
