Logitech Mediaplay Cordless USB mouse problem

[guitargoblin]

Hi, I recently brought a cordless logitech mediaplay USB mouse, at first it was working OK when i plugged it in but since installing the additional software I have no function what so ever. Batteries are fine, mouse is close enough to USB receiver, the set point software recognises the mouse being there and can tell me that the battery is good. Any thoughts? thanks.
