I was editing a layout and my computer crashed. When it restarted i tried to open up my project to continue working on it and a message came up telling me that the document was empty. It said to check the file in a text editor so i opened it in notepad and nothing looked wrong. I didn't change any of the folders or the .xml files. This has happened to me once before and last time i was able to open it with the back up save but this time when it is in a .capx format the message tells me it is unable to open it for unzipping. But if i save it as a .caproj then the same message saying it is empty comes up.
I have found a few similar posts on the forums but they either go unanswered or say to restart your computer. I tried restarting the computer and the same issue came up.
