Strange Punkbuster error

[a_hamburger]

I know this probably was already discussed, but I couldn't find it, so here it goes.

I was playing on a server when I got this error message from Punkbuster:
mods/bf2/std_archive_mod.md5 (len=360)

It kicked me for two minutes. I rejoined, and it happened again, although it took less time for it to happen. So, I went to a different server with a different map, and it did it again. I've also been getting kicked by Punkbuster on BF2142 because of a "Handshake error". If anyone would help me with this problem, I would really appreciate it.

Also, Print Screen has stopped taking screenshots. I would have posted a screenie of the error, but it wont work. Anyone know how to fix that?

try reinstalling punkbuster? check the sticky about PnkbstrA heads up

You are failing an MD5 hash check. This means that either a file is corrupt, has been changed, or is deleted. Reinstall BF2. About the handshake error, try searching. It seems to be common, but I have not had to fix it before.
