"As a result you will not be able to import QuickTime movie files. Please re-install the application to fix this problem."
Which application is it referring too? QuickTime or Hitfilm?
Update: Reinstalled Hitfilm and it's actually lagging more as I'm trying to edit. Someone help asap please.
Lagging but you can now load QuickTime files? Sounds like problem solved.
Next: what is the specs of your PC, CPU, GPU, OS, RAM?
