Can't figure this one out. New computer, running windows 8. Trying to download sound file. Using USB/serial port cable to TIU. I can get as far as loading sound to engine then get error message Unable to continue, no serial port found on this computer. Camera works on ports. Looked under options toolbar and tried looking for TIU, same result, no serial port found. I haven't had this problem before.
Where should I begin looking for problem?
Thanks, Chuck
