Xbox Controller Buttons Not Working with FIFA15

Up until a few months ago I was playing Fifa 15 on PC with a wired Xbox 360 controller with absolutely no problems. Then after a graphics card driver update (using AMD Radeon 7800 series) or at least around the time of the update my controller stopped working
with Fifa 15. The problem with the controller is that only the buttons do not work in game, it appears that the joysticks do work as I can filter between the language options on start up but cannot press any button (X,Y,A,B, Start, Back etc.). I thought this
problem would be pretty common but so far have found no fix at all.

I have reinstalled my Xbox controller drivers countless times, checking for updates regularly but this has not helped. I have also removed any old controller drivers. I can confirm that the problem is not with the hardware in the controller itself as I tested
using > 'Click Start, click Run, type joy.cpl in the Open box, and then click
Properties.' -> from this test all buttons are working fine.

Really struggling to find any solution to this guys, if anyone has any idea how to fix please let me know below as I'm sure there are other people out there with the same issue.

Thanks.

Downloading fifa 15

Bought a new xbox one with fifa15 today. Fifa15 has been installing for 3 hours and is only at 17%...............surely that's not right????

 

xbox controller home button issue wont resolve

OK strange new development/observation

it appears if i plug the controller into the xbox via usb, than still the home button doesn't work, HOWEVER if i remove the batteries making the controller dependent on the xbox for power then the HOME BUTTON WORKS IMMEDIATELY! while plugged into the xbox
with a working home button if i put the batteries back into the controller, without hitting anything, the home button stops working again.

and remember the controller will turn the xbox on via home button even while not connected by USB...

what in the world is up with this controller?!
