Hi Angelo D,
It sounds to me like you may need to manually install the drivers?
If you are going to try this I would recommend removing the drivers first. If you open control panel (make sure you select "all control panel options"), then open "programs and features", scroll down to "Pioneer DDJ_WeGO Driver" and uninstall this.
The try following this link here and downloading and installing the latest drivers for the WeGO:
pioneerdj.com
Once that is done try running Serato DJ Intro again. If you are still having no luck you might want to try it with another USB cable as well?
Let me know how you go,
Cheers, Sam
