I purchased the skylander bundle and can not get the portal to work. I have the wireless usb receiver plugged in the top usb slot of my modded wii. My portable hard drive is plugged into the bottom one and only works in that slot. I use usb loader to mount the skylander disc as the upper left icon that the game name normally shows up on says wii system update. Does anyone have the same problem and have a solution? Is the top usb slot suppose to work for this? Thanks.
