Call Of Duty WAW 1.5 Patch Problem

Firstly, I have downloaded the lastest patch 1.5 for COD WAW, and when i try to play on multiplayer it comes up with an error saying: ERROR: Could not find zone 'D\/Progam Files\Activision\Call Of Duty - World At War\zone\english\code_post_gfx_mp.ff'

Secondly, when i go on Co-op and try to go on the new nazi zombie map Shi No Numa it says i dont have it installed even though i have downloaded the patch.

I tryed reinstalling the patch but because i have already got it on it wont let me reinstall it.

Because its only two file i dont want to reinstall my game, so if you can please will you send me the files.

So i can see how amazing the new maps are!

Thanks
