Don't change the script, just check the configuration.txt file? You surely change :
//Choisir la langue pour les WaitingRoom : (0 = Français / 1 = Anglais / 2 = Espagnol / 3 = Tagalog / 4 = Russian / 5 = Portuguese)
//Choose the language for WaitingRoom
set $EP7_LANGUE,4;
If you only do a reloadscript it'll disappear, you have to restart your server. If you change nothing, change this config to 0 / 1 or 2 and restart your server. In fact dunno why it's set in russian ... I'll change it on the svn to set at english directly.
