that means you didn't run it with the required parameters as well ...
If you have open the explorer window where videomaker.exe is, hold shift and right click, select "open command window here"
Then type
videomaker.exe
path.. where path is what eng.log prints after videomaker.exe, a path to your video directory.
Oh, now I got an idea ... in eng.cfg you have paths for screenshots and videos - aren't they still with the space in the path?
