iTunes/NowPlaying not working since GPU driver update

[CommandaPanda]

So tonight I updated the driver on my GPU (347.09 WHQL for NVIDIA) which has caused my two music players to stop working. I have my own custom made skin as well as Soita which have stopped displaying any information to the skin (my creation was a barred visualiser detecting sounds, it still manages to do that side of things just not display things such as Title and Artist). I've transferred my visualiser to another device without the driver and it works perfectly fine. Anyone know how to fix this? I've made sure iTunes (my player) is up to date which it is. Thanks

When you had been updated the Driver ,did you receive any message of restart your system?because some time we update anything we need to restart the system or program..did you do that?
