It's a program to help you draw isometric blueprints and other lay outs. I got a copy of the program from my tech teacher so I could move forward with the self tutorials, but stupid me I forgot to email myself the tutorial files, so I didn't get any work done. I did, however, manage to find a serial number and key code to install the program, but I'm having trouble with the selection window ehwn I first open the program. It says microsoft isn't able to 'debug' the application, can anyone offer any help?
