The problem I am having is when I run my Arma 2 CO through certain programs, (Such as Arma 2 Launcher) it does not have full quality textures for all Arma 2 models. Such as the weapons, streets, grass, bushes, etc. I really don't understand why it is like this but, before I bought Arma 2, I did infact use Arma 2 Free with Arma 2 OA, then even after uninstalling Arma 2 Free, it still did not give me full textures. Thanks for any form of help.
