    Hitfilm 4 Express does not support AMD APUs. Your machine is under minimum specifications to run Hitfilm.

    It's possible I'm wrong. You might need to wait until Monday for a staff response. They are out for the weekend.

    If the software was running correctly before have you installed or uninstalled any other software or added any hardware drivers?

  •  i updated my graphics card drivers acouple of weeks ago but hitfilm 4 express was still running fine after that and i also found out that there was a problem with my laptops audio and i have now fixed the problem with my laptopbut i still have to check if it has fixed the problem in hitfilm 4 express

  • i also installed software the software is

    Kotobee Authour
