It may be too late, but in future, if the files actually were there, one of the free undelete utilities may bring some success. I'm assuming that Wingz simply deleted them for some reason and didn't do some of secure file wiping for some weird reason. Of course, you have to stop writing to that folder and prfereably to that drive immediately to avoid overwriting what could be recovered. One of the file sync utilities may be able to automatically copy saved files to a different folder/drive. Maybe something to look at if Wings has a habit of going t**s up like that.
