Windows 7: Keyboard Zaer Tarantula recognized as my mouse Razer Lachesis

Hi,



I've just passed on Windows 7 64bits to be able to take advantage of more ram capacity, everything was fine, keyboard ( Razer Tarantula) and mouse ( Razer Lachesis) did work. I decide to install the Razer's drivers of my keyboard and my mouse. I've looked well it were the good drivers for Windows 7 64bit.
At the restart, drama, the keyboard's lights are on but does not work any more as it would! It's recognized as being a mouse Razer Lachesis (mouse i own in that configuration)

Detail pictures: when I press on a touch on the keyboard the logo razer winks??!
The light at the top-left corner "S" is on.

Properties of my Tarantula keyboard how my computer sees it.

In my present configuration I use a Tarantula and a Lachesis, I use the Lycosa awaiting my problem be solved.
I also test with a PS/2 keyboard and a PS/2 mouse

I've tested on WinXP 32bit, same issues. At the boot, in BIOS my Tarantula appears as a USB keyboard, so correct.
In the Device Manager it's like that :

Driver set, the keyboard has the same behavior as on Windows 7; light "S" on, glowing logo and no response from the buttons.
