Well, I had the same problem of being kicked for exactly the same PB 130827 on the Metro/Locker server almost every round yesterday. The funny part is I didn't even log out of Windows, and didn't even use that dedicated gaming machine between playing on that server the day before and yesterday. PB simply decided to kick me by itself yesterday.
After some frustrations, I finally downloaded & installed PunkBuster, added BF4 to it and have it do an update. No trouble after that.
And BTW, my machine has a clean install of Win7, w/ only drivers, TARGET, TS3, Emacs (for editing config files), BF4, and the soon to be uninstalled TitanFall. And now PB, nothing else, clean as a whistle.
