My galaxy s4 wont let me open my downloaded apps

[smm13]

I have a galaxy s4 and it won't let me open my apps that I installed when I go to the App Store it says that all my apps are downloaded but it doesn't give me the option to open them when I go to the home page and I click on the button that takes you to your apps it tells me that I have no apps downloaded so basically when I go to my place store It tells me that all my apps are downloaded but it doesn't give me the option to open them and when I go to my home page it tells me that I have no apps downloaded

When you go to the Play Store it tells you what apps you've installed in the past on that account, not which apps are currently installed on your phone.
