Hey guys. White Rabbit here, just figured I'd share what I learned regarding an error from Punk Buster that I recently encountered.
*If you don't care how I figured out the fix, skip the next part*
I noticed that every time I was on the AKA server, my chat area was flooded with a message that read something like "Punk Buster Server Error: Event Overflow". While the server let me remain on it for a bit, I was inevitably kicked off after about 15 minutes or so. I asked a few AKA members, and it was suggested to check my cache for RO2. The result was a more immediate disconnect from the server, followed by a notification to manually update PB. After looking around, I found the manual update files and followed the instructions, but to no avail.
After some rooting around I found this to be quite useful. If that still doesn't fix the issue, try hitting windows key + r to open the command line, and type in msconfig. Go to the services tab, uncheck the obvious PB services. This will prompt a restart. Restart FIRST, then run the update program from above. RECHECK the PB services that show up on the list, and it will need to restart once more (I know, a pain in the ass), and you should be all set!
I hope this will help anyone with the same issue I was having!
