Je n´ai pas retrouvé l´endroit ou j´avais lu la réponse mais je pense avoir trouvé:
" With the recent PunkBuster updates Even Balance introduced tighter security measures to prevent cheaters bypassing their system. As a result many of you are now getting kicked for Blocked O/S Privileges when playing games with a ´Limited User´ account.
Even Balance are advising to temporarily disable other security type programs you have running such as anti-virus, process guard, SDProtector, etc. to find out which of them is blocking PB´s access to resources on your computer. You either need to run PB without the blocking program(s) or play on non-PB servers.
Another temporary solution to resolve the issue may be to promote the ´Limited User´ account to ´Administrator´ and raise a support ticket with Even Balance ( link below)
Raise a web ticket with Even Balance and quote the 3 digit code you received when kicked and as much detail as possible about your PC and the steps you have taken.

If we get any further news then we will post here.
En clair, il faut que tu ne sois pas sur un compte limité mais administrateur, que tu désactives tout les programmes comme l´anti-virus ( mais pas le parefeu ) et fais une analyse anti-spyware car j´ai vu qu´un certain spyware causait ce problème.
