Hacking Help after 4.0 downgrade

[cr235]

i recently downgraded my wii from 4.0 back to 3.2e and i am not able to play backup discs...
i was able to play every game that i have on dvd-r perfectly and now not 1 of them will work
when i go to load a game up it just says dvd read error

i have installed cios rev 7 and backup launcher with 002 fix

its definitely not my discs as all of them have worked before

any help would be brilliant

Did you install DVDx too? because If you didnt its not going to read any dvds. lol
