Amnesic

When I restart it actually fixes the problem. So what could it be then?

I am sorry for making this a triple post, but I really want to know how to fix this. Even if someone just says they have no clue or maybe a slight idea. I just really want to play again... I am getting bored.

Ok... I reinstalled and everything and it started working all night yesterday. Now it is still saying it has failed to intialize. I haven't added or deleted anything in the addon folder. The only mods I have are FDF sounds, durgs vegetation fix, and arma effects addon. I also have the beta patch installed. But even when I uninstalled the beta patch, it still didn't work. My specs are: 3.2 ghz pentium d 7900gtx with latest drivers

I am currently getting this problem. I was playing perfectly fine and now it is not working. I deleted some addons I have in my folder but I am almost 100% sure that I deleted the right things. Does anyone know what else could be wrong?
