So, i've updated to 4.3U Wan with the 4.3b installer, HBC and all other hacks run normally, with none problems,

BUT, after this install, my Wii don't are reading Wii discs no more. Get the "Disc could not be read"
Gamecube discs run normally, so i got this aren't a Reader problem.
Most of my games are on the HD, but i like to play my SSBB and SMG1/2 originals some times.

Any fix for it?

My wii:
4.3U Wan
All uptaded IOS with Pimp my Wii
Running all the games, except original discs.
