I have just bought a Wondermedia WM8650 for the purpose of using Skype. Skype was preloaded but when I try to use it I get a message saying I need to input my Skype Internet Number which I don't have and don't see why I would need one. I tried unistalling skype and downloading it again through Market but have not been able to do this as I can't get my gmail account to recognise the tablet as one of my devices. Can anyone help please?????
