Acer wireless mouse and keyboard connection...

Question

Hi. I moved my tower and and when I went to use my wireless mouse and key board they were not working? I don't know where the Set up disk is as I have moved house after the inital setup etc. I have an acer system. The wireless keyboard is a Y-RK56A and the mouse is a M-RAF95. It only came with the mouse and the keyboard. I have re booted the desk top but to no avail, and I have tried pressing the connect buttons, again with no response. Any ideas? Mandy
