From Windows do:
Start->Run->devmgmt.msc (or search for Device Manager if you don't have the 'Run' menu enabled)
Under Device Manager, look at Ports (LPT and COM) to see what ports you have. Ensure that your Pronto is connected to the first Serial port that is there. COM1 usually. If you have the Pronto connected for example to COM4 and there is another device connected on COM3..COM1, the software is attempting to connect to that device instead of your Pronto.
