First of all: Hey all!

Now to my problem.

I tryed to install CFS3 but I couldn't finish theinstallation.

It reaches to 97% but then freeze and says some error about a file msh2 or something like that.

I tryed installing in drive C,D and E with no luck  :'( :'(
Which means, I can't patch the game, install new mods(Korean Campaign is one example, I really wanna play it but no luck :( )
And I am having some problem that I have no sound in the game.
But when I play like HL2 PF IL2FB HL2:DM CS:S
And that games, I hear just fine.
But on CFS3, I hear nothing.
But what is strange that, I had sound like the day before yasterday.

So, please help me.

Sounds to me like you have a corrupted file on your CD. To get a replacement you'll have to contact Microsoft about it. Good luck.
