Windows 7: Nexxt Bluetooth dongle not working on W7

Hi, I'm new here but I've been looking for a fix for this for a while now.
I have a Nano Bluetooth USB Dongle from Nexxt Solutions. This is a plug n play device, so it didn't come with any drivers. It used to work great with Vista but since I changed my laptop's OS to Windows 7 Unlimited, 32-bit, the computer just don't see it at all. I already looked in Device Manager and it just doesn't appear anywhere.

I searched in manufacturer's website and the only driver they had there was an outdated version of the bluesoleil drivers. I tried them with no luck so I tried whit the latest update of the drivers and no luck either, the software installs but the computer still doesn't find the device.

I also tried the broadcom drivers for both Vista and Windows, as recommended in another thread, but they don't find the device either.

Is there anything I'm not seeing or doing wrong?
I will really appreciate any help ;-)
