iTunes store is up to date, but is just a white screen

I updated my iTunes store and it is up to date. Shortly after this my iTunes store stopped working. It's just a blank white screen. I googled it and I found one, but it said to make sure it's up to date. I already had downloaded the new update but I double checked and it's defnitly up to date. I really don't know what to do and I really need to fix it ASAP!!! Please help!!!
