i updated numbers on my iPad and now it is not working

Try deleting the app and then reinstalling it.

If i delete installed Ap, files will be destroyed No ?

Yes - you will need to back up the file(s).

Before deleting the app, try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset. This should have no impact on your data.

I have the same problem... Numbers, Pages, and Keynote no longer open. I really don't want to delete/reinstall. What to do?

Have you attempted any of the suggestions already posted?

Yes. I have rebooted several times and the problem is the same: launching any iWork app opens for a moment then crashes to desktop. The app is still in the selector but it cannot be opened.

I am reluctant to delete and reinstall until I can verify that the files are available in iCloud. They should be, but I don't have time atm to dig them out.

More info: This is a generation 1 64GB iPad running IOS 5.1.1. This week the eBay app also fails to launch. But for that my theory is eBay added camera support for their new scanning, but this iPad doesn't have a camera. eBay is also mission critical as we are wholesale buyers for a retail store. Ebay, Numbers, Keynote and Pages all fail. All other apps seem fine. Maybe Apple changed something in their sdk which is breaking these new apps. For memory: About reports 40GB available. Maybe this iPad has a memory problem... is there a memory test to run?

Having iWork crash like this is unforgivable. These are mission critical apps for me. I need them in real time to run our store. OTOH the data is mostly temporary and not that valuable, except for that great presentation I made on how to save Bliss, Michigan, from windmill farms for the planning commission, only to have Keynote not start. Plus a couple of spreadsheets whose content is a vague memory. Hopefully they will be in the cloud.

I am hoping Apple is aware of this issue and working on a patch.

btw... my wife's idea is to use the Android pad instead.

Not sure why you think anyone cares.

As for the iwork issue, no, its not a compatiblity issue with the first gen iPad or iOS 5.1.1, and ther isn't a need for Apple to patch anything. Its not a widespread of general issue, its isolated to you in the case. They run fine on my old one. The ebay app itself should be fine on 5.1.1, just won't run the camera function.

Like you will need to consider a restore of the iPad: http://support.apple.com/kb/HT1414

Thanks... no offense meant, I thought it was amusing that to her it was as easy as that. For eBay, it is, almost.

I'll look into a restore. Wonder what caused the issue, though.

I have the same problem since the Numbers update on my Ipad,

I have found if I go to settings, Numbers then Turn off use icloud, I can then use numbers.

This how ever is no good for me as all my documents are in icloud so I cant access them.

Thought there my be a corrupted number file But even if I move my documents from icloud to my mac storage, Numbers wont't open when icloud is in use with Numbers.

After several on-line chats with support and aparently icloud teckies are looking at it, I am still none the wiser and its been 5 days now.
