The Other Guy

I just reinstalled Call of Duty (the original) on my computer. While I was playing online I came to a server that downloaded a "modern" weapons set. The only problem is it has changed the names of the old weapons to modern ones and it has also changed the sights on the scopes of the sniper rifles. It doesn't really affect gameplay, save the sights, and it doesn't do it in multiplayer mode, but it's annoying the crap out of me.

Does anyone know how to make it go away?
