Strange, that's the latest version but I don't get that error.
I do note that the codec used by this video file is somewhat confusing to the program -- it does have a little bit of trouble with the file (it can't seek to the last frame and the video wont pause properly within the main media view tab),
but it will layout and print from my copy of flipsuite, which is same version as yours.
So I don't have a great answer for you, however a workaround would be to try to use a video conversion tool to convert the video file into a more standard format (like a standard avi file (this file is an AVI file but its H265 codec)) and then try loading the conversion file.
Sorry I don't have a better answer.
