About the files, then I don't think it's the req editor. It could be possible that your files got infected with something. If it's a virus, then you could get some serius problems checking the files at another computer, but I'm afraid that you have to take the risk at first round. Do you have an old computer or a download computer which you wouldn't mind if got infected? I'm talking about actually be prepared to reinstall everything if something goes wrong, and then test all you pictures on another computer.
