Yea I did have some problems setting mine up. I didnt have the mouse problem your describing though. Have you managed to connect it to the BT dongle? I found that it had to be installed on a front USB port on my case for the signal to be stable. When you are using the mouse the charge lights should be on constantly until you take your hand off the mouse, if they are not i would imagin that there is either something wrong with the charge unit or faulty batteries. I assume that you can connect both the keyboard and media pad OK?
