This is a repost but I was having the same problem downloading that file. Here's what I do to get the game to work (it works every time now):
I encountered this problem as well. I wasn't able to get the shader files from Rapidshare but I did fix it. Haven't had any problems since I started using this method:
First, you have to have the original /Mods/BF2/client_shaders.zip in that folder. If you don't, you need to reinstall BF2.
Now, make a back-up of that file and keep it in the same folder.
Second, reinstall FH 2.25. Make sure you deleted the .tmp (mydocs/bf2/) and cache directories in your My Documents/Battlefield 2/FH2 folder.
Now with it fully installed, go to your /Mods/FH2/ and make a back-up of client_shaders.zip.
Run the game. Should work. When it inevitably breaks again (crashes out), you need to do these three simple steps and you will be good to go again. I have to do this almost every time I start the game.
1) Delete the client shader file in /Mods/BF2 and replace it with a copy of the backup (keep the backup NB!)
2) Delete the client shader and the client_shaders-backup files from /Mods/FH2 (NOT your backup). Replace with your back-up (just client_shaders.zip).
3) Delete any folders in your My Documents/Battlefield 2/FH2/Cache folder.
Let me know if this helps. Cheers!
