Although I have successfully uploaded and downloaded files to my TSU7000 since installing ProntoEdit 2.1, I am unable to do so now. After my computer establishes communication with the 7000, I receive error message: "an error occured while converting this configuration file for use by this device."

I started receiving this error after adding to my ccf and learning new remotes. Do I have a corrupted file? Will I have to recreate everything from my last good file?
