Like what was stated, the error notification has no Bering on the programs functionality. If your having problems with fifa it's more than likely an issue with HIDGuardian if your getting double inputs. Try reinstalling HIDGuardian and take a look at this thread for more info.
Wow... drama queen much? Where is your compassion while I deal with much more serious things than your video games, like the fact my mother has been in the hospital since January. Talk about a lack of humanity... The blog tells you how to disable the 403 error from bugging you, beyond that it is very clear that the 403 error has nothing to do with the operation of the program or controllers, it is a error from not being able to fetch data from the server. That is all. Hardly the end of the world.
