Whys isn't my tablet letting me do anything with Google?

[AC Question]

My tablet isn't letting me do anything with Google.

I have a Samsung tablet 2. When I go to "my apps" on Google Play, it says "Authentication required. You need to sign into Google." and its pissing me off. I've done everything I could, I tried adding an account, but it says "Couldn't sign in. This account already exists on this android device." I can't find anything online, and I don't want to reset it because I don't want to lose all my pictures. Please help, thank you.

Welcome to Android Central! Are you able to use all of your other Google apps, like Gmail, Google Calendar, etc.? In Google Play Store, when you swipe in from the left, do you see your Google account at the top?

Also go to wallet.google.com on your computer browser, and make sure you have a valid credit card associated with the account.
