Adding additional XVM account/player

[ragnar704 0]

My son and I both play WoT on my computer, but with separate WoT accounts.  I run XVM on my account when I play WoT, but I can't figure out how to add his account.  When I go to http://www.modxvm.com/en/, my account is automatically recognized, and even if I log out, I can't figure out how to add a second player.  I'm hoping this is just a stupid question with an easy fix!  Any help is greatly appreciated.  :)

Relogon on the WoT portal or just use another browser.
