Hi Vito,
The MSP430 Has to enumerate as a port on your PC.
Please check, in manage my PC --> port
Please see this section of the wiki for the hyperterminal settings: http://processors.wiki.ti.com/index.php/CC3000_Basic_Wi-Fi_example_application_for_Launchpad#Configuring_the_HyperTerminal
If it doesn't work, please try reinstalling the MSP430 drivers
