crashing, unable to use Hitfilm 4 pro

Hello everyone.
i haven't used hitfilm in a while, i wanted to do something recently but i'am unable to use the software (Hitfilm 4 Pro), it keeps crashing.
if i try to load a project: crash
open a new project: crash
even if i simply close the program after launching it without doing anything i get an error crash message.
i installed the latest hitfilm update, i tried to do an uninstall and reinstalling it, but that didn't help.
graphic card drivers are up to date
all latest windows 10 updates installed
my system:
windows 10 64 bit
16 Gb ram
Amd Fx 8370
msi lighting 290x 4 gb
someone with an idea on how to solve this issue?
thank you all


  • Hello all, 

    I was able to resolve the issue myself, a defective/corrupt Database "cache.db" file was the source of all issues as creating a new one did resolve everything. :)

  • @Soundivad ; Thanks for posting your solution.   Sorry you had to figure this out yourself. 

    I assume the offending file was in this location?   C:\Users\<your account>\AppData\Local\FXhome\HitFilm 4 Pro\cache\Media  

    I'm on Win 7 so the location may be different on Win 10.

  •  C:\Users\<your account>\AppData\Local\FXhome\HitFilm 4 Pro\cache\Media  

    yes this is the location
