Global Conflict

This just started up today after having issues with my ISP (where i have to use a proxy for a day or two) as i couldn't get some webpages.

Now is this because of this, if so how do i fix it ?

Maybe your ISP have some of the ports closed which are needed for BF2? Check with your ISP and see if thats the case.

You can get the port numbers from the EA BF2 forums as thats there I found them where I was having a simular problem.
