I don't dare to reinstall, because I'm afraid of losing all my created profiles

This seems to be caused if you have more than one hardware device that is opencl capable. I will update FastFlix to just use first available (as ffmpeg doesn't have a clean way I know of to list them out)

@Battlestar1965 you can copy the fastflix.yaml file in %APPDATA%\FastFlix (can put that in top of the folder bar and hit enter) to a second location to ensure you don't lose those!
