I've been working on a comic strip for a week and had come close to completion today. I lost track of time and my iPad battery died right in the middle of me working on my project in Adobe Ideas. After connecting my iPad to power and booting it up again; i launched the application to discover that my project no longer showed a thumbnail preview. Out of curiosity i tried to open the project and all it gave me was "ERROR Could not open the page. The operation couldn't be completed. (Cocoa error 259.)" I had tried to salvage the project from adobe ideas on my iphone, but was only able to successfully email a PDF of an older version of the project before the Cloud updated the project and overwrote it with the corrupted one. I've tried duplicating the project, changing the name of the project, logging out of creative cloud and signing back in; nothing seems to fix the issue. I did manage to log into creative cloud from my computer and download the .ideas document to my desktop. The document won't even open up in adobe Illustrator, it actually crashes the application in mid attempt. Someone from support, please tell me there's a solution or some way to salvage this file; its an important piece to a set that im working on. I've invested the majority of my day toward this and it disturbs me greatly that it was so easy to lose something like this through Creative Cloud. I do ALL of my illustration work on my iPad and would like to prevent this from accidentally happening again.
