If your image is corrupted I would start by restoring the image. Once the image is good you can reload from backups.
To get files from Roboguide to a robot I usually just save them to a folder on my desktop. That way I can transfer them either with ftp or a usb stick. I think there is a way to do it inside Roboguide, but I've found that I use it so infrequently that I don't bother trying to remember.
