Can you open the document in Preview or TextEdit?
Right click (or control click) on the document in Finder and Open With
If that works, you can copy and paste into a new, blank Pages document.
How large is your document? Pages does not handle large documents well. If it is large, split it into several smaller Pages documents.
Thank you Yellowbox. Sorry for my delay in response... I don't have steady Internet access as I'm traveling. I have tried to open in preview with no success and TextEdit brings up something but it is not any kind of letters, it looks like a strange code to me. The pages file is 246kb. I tried running the scrips from this thread http:/https://discussions.apple.com/message/16077040#16077040 and was successful at pulling up all of my old versions of pages files from the hidden folder. The 3rd script worked to open and view old versions on uncorrupted files... but every version of my corrupted file still came back with "the document does not have a valid file format." Some of these versions were over a week old so I asume that the file format issue effects all versions of the corrupted file. Is there a any other ideas out there? Data recovery software, etc that will let me get to the text? It's a lot of writing... months or work, and would hate to lose it. I'm not a big fan of this versions idea... now I always make a duplicate as well as the version save.
