My Wii is running 3.2U with D2Pro 5/9 Wire. When I got my Wii Fit the I let it update all the way to 4.0 and ever since I cannot read discs. I have since downgraded to 3.2U and I have updated my firmware on my D2Pro. It says "unable to read please consult users manual". I have tried using backed up copies that I have as well and no luck. I have even tried running it using wiigator. If anyone has any suggestions on what I can do I would greatly appreciate it! THANKS!
