I have been working on this file for a while now and have never had any problems opening it to have it edited. The last time it was edited was 10/19/2013 but on 10/20/2013 I tried to edit it and an error popped up saying that the file cannot be opened for editing. I have tried to edit it repeatedly but it still won't work. I have no idea on what to do or how to fix it. When I go to documents and click on the file it loads on the web app and I am able to view it but when I pick the editing option it will not open. I do not have the full version of Microsoft word only the app so I only choose the option to "edit in word web app" I have only edited it once on the full version but it was from another computer. Can someone please help?
