This does not describe your problem at all.

Do you have the correct port selected in the IDE? It will be listed in the "Device Manager", under "Ports". Make a note of which port, then ensure you have that port selected in the Arduino IDE.

Also, your modified "Blink" sketch will no longer flash the LED. It will light it, then it will remain lit forever.
