I had a problem on my Windows 7 computer that let me save the files, but when I'd go to the folder in windows to copy them to my other computer, the folder couldn't be accessed or was empty (can't remember which); but if I went into the program I could still access the recipes. Ended up being some sort of giving the program privileges to change files on my computer, but it still didn't show the recipes I'd entered, so I had to go save them over again once I gave it the correct permissions. I also saved them into a folder that I'd created through the windows browser instead of when I was in the program saving the file.
Try right clicking on the folder icon that you're saving to and check the permissions, and right click on the program icons and check the permissions there. There should be an option to allow the program to have read/write options.
