so forgive me if i am stupid, but i just installed the program, and downloaded 1.6.1 on my macbook pro. i then hooked up the hard ware and tried to run the program but i cant get it to run. i see the icons on my desktop for the programs i just loaded, but none of them are the actual "scratch live" red dots icon......does that mean anything? help please!

Click on the finder and look for a folder named "Applications". The Icon for "Scratch Live" should be located inside of there.
