Not able to upgrade Keynote

[Agnest]

Hey guys, I have a serious problem here. I have upgraded my Ipad2 to ios 6.0.1 and also update the keynote to the latest version at 1.7.1.
However, it had been hours the keynote icon remains "Loading" and no update has been done.
Hence, I delete the whole thing and re-install again. But the problem persists.
I am going to make a business presentation tomorrow, anybody can help me to resolve this problem?

I am going to be crazy, so regret to do the updates..

Thanks in advance if anyone could help me!

Things to try.

If you have not done so since the iOS update, reset the iPad. Hold down the power and home button until the Apple logo appears.

Go to the App Store. At the bottom of the Featured tab, find your Apple ID. Tap it and sign out. Tap it again and sign back in.

Now, once you are on a solid wi-fi network, try the download again.

Good luck.
