I connected to BBA1 after re-downloading the .pk3's to play, since I have reformatted.

My console is rapidly spamming my client with this...
Punkbuster Client: O/S Exception Notice

Then I get auto-kicked for Losing Key Packets.


Anything I can do to fix this? Thanks.

Weapon: turn off PnkBstrA.exe and PnkBstrb.exe
Some other software programs such as virus scanners, firewalls and Internet security software packages are suspicious of any new services and kernel drivers when they are first released. Some of these will block our new components thereby causing the "Losing Key Packets" kicking. Until these various packages are updated to correctly identify PnkBstrA.exe, PnkBstrB.exe, and PnkBstrK.sys as components of the PunkBuster Anti-Cheat System, players who experience PunkBuster kicks due to these conflicts need to either manually adjust the settings of the other software running on their system or disable the other software while playing on PunkBuster enabled servers. The new PunkBuster components make use of network resources and also frequently update files in the Windows system folders. This activity triggers warnings or blocks by some other security programs, some of which consider all unknown programs as threats or malware. Our new components are simply extensions of the existing PunkBuster system using new services and kernel software drivers, and are each signed with Verisign / Authenticode digital signatures for verifiable authenticity purposes. Most major security packages do not block our new components; users with other software that causes these conflicts should contact the vendor of their security package and request an update to correct this conflict.
-try to install Service Pack #2,
-check cl_maxpackets.

Try doing a manual update from punkbuster's website. Even if the update isn't recent, as long as it is the latest on the website, then update all of the components manually.

I had that same problem a while back and this fixed my issue.

Oh sorry I should have updated this.

I tried what Caroline said about the Service Pack 2, and 1 other big thing I think, and either or both of those got it to work.
