I have problem (FT8)

Hi all
Can anyone help with my problem? I have just acquired a FT450D tcvr and am trying to use FT8 on it. I have bought a DC11F interface cable which connects into the data socket on the back of the rig going to the audio in and out sockets on the laptop. I have downloaded the software, and installed a package as instructed for Linux, followed the installation guides from the WSJT website, and others but cannot get a green test CAT. Keep getting "Rig Failure Hamlib error:IO error while opening connection to rig"
I am not very computer or digital literate, I still like valves! So can any of you young computer and digital modes experts help before I throw this computer out the window and vow never to have anything to do with computers or digital radio again!!
Hopefully hanging on

    On the FT-450, use the CAT connection for CAT control to/from the PC, and use the Data socket for audio in/out.

    It takes at least 2 cables to have CAT and FT-8 working at the same time.

    If I remember correctly the CAT cable will go from the CAT connection on the back of the radio to a USB port on the PC. I used the RT Systems CAT cable and it works well. eBay CAT cables are hit or miss.

    I used the audio in/out from the Data socket to the PC's sound card. I used an external (USB) sound card so I could still have the PC sounds on the PC speaker and FT-8 audio handled by the external sound card.

    If you don't want to mess with PC sound cards, you may want to look at a signal link box, I hear them make the audio connection easier, but they cost more.

    Good Luck,
