!!!!UPDATE SOLUTION!!!!
Hello all,
I know that many of you, myself included, may have been experiencing trouble updating to the current version of iWorks with Mavericks. I have found a solution.
TO DOWNLOAD THE UPDATE, REGARDLESS OF HOW YOU HAVE iWORKS(APP STORE/DISK):
Create a new user account under System Preferences, it doesn't matter the type of account. Once you create this account, log in with the same Apple ID you use for purchases. Go to the Mac App Store>Updates and Voila, updates are available.
I have talked to Apple and they are aware of the situation, the engineers are on it and they are planning on having a solution (If mine doesn't work for you) by Friday (10/25). They will probably provide iWork owners a redeemable code, or release an update via Apple.com/support.
iMac, Mac OS X (10.7.3)
