Is it possible for my to use an RS-232 9 pin to 25 pin cable in my com3 port to execute this download. My laptop only has a 25 pin port, not 9 pin port. And how come when I hit download, after 1 second, the entire program shutsdown, and it keeps doing that?
Yes, as long as the receiver you connect to does NOT require a null modem cable. If it does require a null modem and you hook it up, you might screw up your receiver.
First find out what type of cable (straight-thru / nullmodem) your receiver needs before you do anything.
