Client File is Corrupt after Chams

So i've downloaded an RS.rez file and placed it in my game folder.

When i run Combat Arms EU after logging in i can see my character with the chams (it works) but i get an error message with "Your Client file is corrupt" and it closes.

How can i fix this?

Take some other .Rez cham mod.
I had that with some of them but i got the Green/Purple(lavender) to work.
