Sims Freeplay Cloud Save Issues

So I have the Sims Freeplay on a crappy (free) LG Tablet, LG GPad F2 8.0. I have it on an SD card, but I still want to use the cloud save. I created a facebook account just for this, but when I went onto the sims freeplay, it says "sorry, there are no social networks available" or something like that, on both account manager and cloud buttons. I tried google play games, but when I entered my email, it would load, but then it would go back to the thing where you type your email. It eventually started saying that my account didn't exist, but it did. I spelled everything correctly and all that, but i eventually gave up. I left the app to find it was no longer there. So google play games is not an option. I am guessing it is an age issue, I don't remember what age I put in though. I have read threads and articles on this and most of the reasons are the age that I put in. But their only way to solve the age issue is to uninstall then reinstall the app. But to use cloud save first. I NEED TO FIX THE AGE TO USE CLOUD SAVE!!! I can't use cloud save and then uninstall the app and then reinstall it to use cloud save. NONE OF THIS MAKES SENSE HELP ME!!! (sorry if what I just explained doesn't make sense)

So the questions are:

How do I fix my age without having to uninstall the app?

Can I uninstall the app on the crap tablet but it will still be on the sd card? (if i uninstall it with the sd card in)

Will I every be able to use cloud save without losing my game?

If I uninstall the app, will the data still be on there because of the sd card?

How would the sd card thing work? like if i uninstall it and stuff, how do i get my data from the sd card on there?

Sorry about all the stuff, words. I want the cloud save thing because I would rather play the sims freeplay on an emulator, on my new MacBook air, and i can't put an sd card for android on a MacBook air.
