ArmA2:CO Won't Open

[fusion3gz 0]

Hello, my name is Devin and I seem to be having some problems with my Arma games over the past couple days. I was able to play both Arma and DayZ perfectly fine untill I went into my folder and deleted the SweetFX mod that I had put in there to improve my graphics. The reason I took it out was so that way I could get better FPS in the new DayZ 1.8 patch. After doing this I was able to play dayz fine as well as the dayz mods. Although when I went to open ArmA2:OA the game wouldnt open. I then tried to open ArmA2 and it would not open as well. What happens exactly is when I open ArmA the checkboxes appear but after the checkboxes are done it seems like the game tries to open but it then closes down. I have spent hours looking for a fix for this and I havnt seemed to find anything. I have tried reinstalling ArmA2:CO and uninstalling it. Deleting all the files that have anything to do with ArmA. I have even gone to the extent of manually installing every single patch up to date.I now also can't even join dayz. It will open the game itself but then says I am kicked off the server. Another thing is when I join a dayz server it says "addon requires CAMisc_fix_A2FREE" I don't know what this means.

 

Things to Know:

I bought the game through Amazon (It was cheaper at the time)

Both ArmA2 and OA are up to date

Try a clean Nvidia GPU driver install.

How do I do that?

So I googled how to update the driver and I did, restarted my computer and now when I join a dayz server I get kicked for "addons/ca.pbo"
