It's so cool when this happens that I can't stop crying

So, a few months ago I cleaned up some hard drive space by deleting some redundant movie project files. I wasn't planning on altering the projects any further and had already published them out to .mov files. So I thought. I'm not entirely sure what happened, but the files that used to work on their own now seem hungry for all the source files, and are only 30k in size (certainly not quite what you'd expect of a 6minute full screen video). So, I'm suspecting, that I inadvertantly deleted the entire project and the published file, keeping the key file only. Fun. Looks like I'll have to do a new project for the film festival in, oh, a week.
