getting a dvd error 972

tried to re-install custom ios and no luck, now backups wont play at all, wondering if to uninstall neogamma r6 to be honest,

had some outdated backup launcher (banner has now dissapeared all it says on about is wiigtor backup launcher and graphic NeoRame and autoboot Forsaekn)

3.2E software on PAL Console.

noticed though i can install custom ios on ios35 but not 249 and as mentioned wont load any backups now, kinda screwed

Question is how can i fix it? should i uninstall custom IOS ?? or uninstall NEOGAMMA R6???

Thanks in advance
