Numbers asking to re-open the app again and again and never opening

Hey Muaath,
I understand that you are experiencing an issue with Numbers on your Mac. I know that you are in the process of troubleshooting it by deleting the app an downloading it again, but it is asking for you to purchase it again. That may be fixed by going to the Purchases tab in the Mac App Store. Take a look at the quoted section below to get it sorted out.
Download past purchases from iTunes

From the Mac App Store

1. Open the Mac App Store.
2. From the top of the window, click Purchases. Your purchased apps will appear.
   
3. Scroll to find the app you want to download.
4. Click Install or Download to the right of the item you want to download. Your app downloads to your computer.

Let me know if this works or if you are still not able to download Numbers again.
Have a good day

If you've been able to launch Numbers successfully in the past, and it's only now exhibiting problems, then it may be trying to open a document that somehow became corrupted. So assuming you've already tried shutting down and restarting your Mac, you could also try holding down the shift key when you double-click the Numbers icon to launch the app. This will prevent it from trying to open a corrupted document. Sometimes I've found I can get Numbers working again that way, and even open the document again from within Numbers via File > Open.

Hi Muaath,
​Glad to hear that you got it downloaded again and I hope that Numbers is working for you.
