Re: [FAQ]Updating Punkbuster
Punkbuster has released an update that should help. Further information is available here: http://www.evenbalance.com/index.php?page=support-bf3.php
It says:
We are aware that some players are experiencing crashes in BF3 after Monday's PB Server update was released. These are players that used PBSETUP to manually update their PunkBuster for BF3.
***** To eliminate the crashing, these players should find and delete any pbsv.dll files located on their hard drive associated with BF3 (use the Windows search feature). Do not run PBSETUP again after the deletes or it will recreate the problem. ******
The crash prevents our auto-update and the file deletes are necessary to resume normal operation.
However, as they have now released an update, you should be able to manually check for an update via the pbsetup file and it should take care of the problem.
