Vista - Excel HDTV USB2.0 TV Stick ,"Cannot support card or Driver"

Hi all, can anyone help ..

I have an Acer 5620 laptop with NVIDIA GeForce Go 7300..with Vista Business..
I am trying to connect an Excel HDTV USB2.0 TV Stick but when I run the
DigitalTV program "Cannot support card or Driver"..I have tried updating the
driver and the usb is seen in devices but I still can't get it to work.. Any
Help Please..

Thanks

Oh and when I initially power up the following is displayed
"HotkeyApp has stopped working" and "cannot find device(C:\Program
Files\MCECIConsole.exe)"

I read somewhere that I need to change the computer driver settings to
standard .. Is set to ACPI x86-based PC .. Is this safe and how do I change
it ?

All I want is TV on my laptop is that too much to ask.. I have tried a
number of different TV sticks and nothing seems to work.. Please can anyone
help..??

Thanks

You needs to change your graphics-card to run Vista Aero or it should work
with your Vista-version,
try to change your theme and connect it again!
