ATI Tool problem

[liveforeva]

Hi
I am trying to overclock my 2900XT using ATI Tool 0.27, but every time i load it up i get a message saying The kernel Mode driver does not seem to be running.
A device driver is required for communicating with your video hardware.

And ATI tool doesnt detect my clock speeds.
Does anyone know how to solve this ?

I am using vista 64 if this helps.
Thanks

The only problem is now though every time i want to use ATI tool i have to keep disabling signature enforcement every time i start my pc.
Is there a way to permanently disable this ?

Now that i can use ATI tool im having another problem
Every time i try to overclock it by moving the core and memory bars they automatically reset themselves.
And if i tell it to find the max settings i get a message saying that theres not enough power and my card has been put on minimum settings.
My power supply is a ATRIX 650W Blue Transparent, it has got one 6 pin pci-e
connector and i am also using an Akasa PCI Express 6-Pin to 4-Pin Power Adaptor.
