I'm not sure if it's my computer or the set, but when I put the USB cord into my PC, nothing happens
! However, I'm sure that it can record them somehow.

I have the same problem.... the instructions specify that the screen module operate in a Windows XP SP2, Vista, or Windows 7 ProfessionalUltimate... and it says its its not compatible with Windows 7 Home

... And I operate in Windows Vista Home Edition

So, I too connect the USB cable but appart from a notice that a software is being installed, of which you get no indications how its called or where its being stored, nothing else happens, although instructions specify that you can access the connected screen module from your workplace (i assume it means my computer)...
have you tried another USB cord? or can you? what does the cord look like?
you can see the cord in the following pic, and yes I have tried three other cords...
