Ok, soooo I have spent the last several days working on a rather detailed sketchdump (which was starting to become more like a finished picture of a ton of my characters) and then my dumb computer decided to corrupt my file. It's a SAI file, and now whenever i try to open it, it gives me a "Cannot open Canvas" window. apparently my file is "broken" or some crap like that. It was working FINE when i saved it last night, and now i have no idea what to do about it. I'm going to try and either run the disk check or the start-up repair on my computer, and see if that does anything. In the meantime, if anyone out there has any ideas on how to fix it, I would be eternally grateful
