Help me pls!How fix that problem.I installed game,updates start (PF_01.ZIP) 448MB my speed very slow and when its 47 mb its give me error Cannot open zip file[PF_1_0.zip]

What OS do you have and do you have a zip editor installed apart from the windows zip program?

What is OS

Operating system, if you have Vista then you have to launch 2 loaders for it to work, one that loads auto and the other that needs you to allow it to run (uac on, otherwise it also starts automatically).

I have windows xp
Before i never have this problem with kwr

On XP this never happened to me, try getting an updated game folder from a friend or reinstall - there is not much more that I know that can help on XP.

Get a better net. Or download it in another PC so copy and paste to yours.
