Disconnected from Play Store

a few days ago i tried purchasing and when i tried to connect it to my e-wallet, they linked it up with my other email and so i cancelled it. since then my candy crush app has been disconnected from the play store and i tried everything from clearing caches to finally uninstalling the app. when i tried to reinstall it back, it won't download nor load. i tried downloading other apps and it works just fine. please help me on what to do since i nearly win the weekly competition and i want to keep it check before this week ends hahaha. thank u!
