I've installed & registered the Hitfilm Cinema style pack in Movie Edit Pro Plus. I can see the options to use the FX. I click on a video or picture & then apply the FX from Hitfilm Cinema style pack. The settings for each option appear as normal in the upper right corner (1-100 or whatever scale). However the screen is always black & I can never see the output from changing the parameters. Any ideas? Using win7 home premium. other plugins are working ok. Hitfilm was registered successfully. The black background is the video clip that the hitfilm cinema plugin was applied to.
