napalm ps2 cd patcher

[balmung]

hello,
I'm having trouble playing backed up games with this patcher after i load up gameshark2 v.2 i press x ater i swap the disk without pressing te eject button and it just brings it back to the ps2 load cd screen and says theres a dvd and i press x on it and it brings it back. I have tried AddzerO also but that says errorcode"5" whenever i try to patch the game, some games work, but others don't, does anyone know what's wrong? or help with addzero would be nice, thanks
