In Cal today I was playing with my clan mates and then all of a sudden... I shoot someone, it kicks me for this message -INIT FAILURE- This problem only happens on specific server and I already reinstalled the patches. Whats up!
Maybe try a PB update. It may not be PB though. if it isnt you may need a client side mod of some sort or PB may think something in your CoD is used as a cheat. Try reinstalling CoD if nothing else helps.
Init failure is pb failure of your computer failing to communicate with the master server, has nothing to with a cheat. It could be caused by a couple of things (i.e router, firewall, connection, etc.)
If this problem hasnt been fixed download http://www.evenbalance.com/downloads/pbweb.exe put it int he pb folder of call of duty and run the program, this will force a update of the punkbuster software thats on your pc.
