rought old man drawing

i just downloaded the trial program to see if I like it. I can open the tutorial, but the images won’t appear. My computer says it does not recognize the source. Help please. Thanks.

Did you extract all the files from the zip file after downloading it? Double-click the zip file and it will open in Winzip (or whatever zip program you have installed). Then click Extract All. This will create a new folder with all the files in it. If you run them from the extracted folder, do you get the same error?
