Why is Hitfilm 4 Express doing this?

Every time I open up Hitfilm 4 Express it freezes, becomes unresponsive and then finally runs correctly. Also every time I import something it does the same this as when I open it. My computer has 16 GB of RAM and it used to run fine

    If it "used to" run fine, what other changes might you have made? Have you installed new hardware, software or the Windows Creative User Update? 

    "16 GB RAM" tells nothing. What's your CPU, GPU, OS, RAM and storage? 

    What is the format (codec and container) of your video clips and how long are they? 

    Are you still on Hitfilm 4 or Hitfilm 2017? Hitfilm 2017 has some new code for dealing with VFR footage which is causing slowdown on file import. The devs are working on optimizing this.
