After 7 hours of work, pages reverted to the original document! So much for saving every 30 seconds. All my work seems to be completely wiped away! Panicking! Is there anyway to retrieve it? Desperate!
If you have iCloud enabled for Documents & Data under your settings you may be able to retrive your work from www.icloud.com on a PC or if you have iCloud enabled in OS X Mountain Lion you should be able to use Spotlight Search (CMD + Space) to find the document by name.
