I recently bought wave pad and have enjoyed using it, however, when I try to transfer the files to my digital recorder they do not transfer. The funny thing is they actually show up on the digital recorder's files when the recorder is connected to the computer. however, when I disconnect from the computer they are no where to be found. I am wondering why the digital recorder doesn't hold on to them so to speak. I am not sure if it has something to do with wave pad or with recorder. The recorder uses wma files, and my files are saved in that format. If anyone can give me suggestions I would be grateful. Thanks. GM
