Tengu,
After downloading the programme\software, I take it that you opened the program from programs list or desktop.
After opening the program you will find a "HELP" section, it might seem a bit unwieldy at first but takes relatively little time to become familiar with it, play around with it as you really cannot do anything 'wrong'.
BTW, did you download it to PC\laptop or are you using it on a tablet or a smartphone?
