Hi. I'm having problems with these two systems. I have Word 2007 and recently I created a document and uploaded it to use in a group on Facebook. There are 3 other administrators in the group that have access to the document to add things and edit it. Well one of the admins recently edited the document and saved it to the group but he has Word 2013. So when I went in to edit the document and tried to save it, it won't save and I don't know why. I can edit and save any of my other documents on my computer with no problem. So I'm wondering if there is something that happened when he saved it that caused it to not work with Word 2007. He said that when he tried to save it, it wouldn't allow him to save it unless he answered yes to the question about keeping "modern format" But I didn't think that would have anything to do with why I can't save it. Any suggestions or help would be greatly appreciated. Thanks.
