Help with Battlefield 1942, "Data differs from server" error. Re-patching the game?

I downloaded a blood patch and now I get this error message when I try to go onto servers. I was trying to figure out what the problem was and discovered that I could play some servers. I am not sure yet if this is because of "punkbuster" or "pure" but I will try to figure that out and add details. I also think it might be a good idea to re-patch bf1942 but I am not sure how to remove a patch. (EX: 1.6, 1.61b)Help with Battlefield 1942, "Data differs from server" error. Re-patching the game?
You Know what, I have downloaded this for free before an hour.

You can download it directly from this single link. But the only thing is you must install their toolbar once. But you can have what you want.
