sorry i should have realised u would not be able to get in without the book, the key, etc.
if i were in ur position i would restart the sentinel island bit, does that change anything?
maybe download a patch to the game if there is one...
to be honest there is a slim chance of u dealing with this because the game is so rigid, all u can do is walk up to the elrith guy.
Here is an idea - try either choosing hermosa again or choosing kenneth to duel her, maybe when she kills him her memories will be jolted.
Just try that, because its either that or restarting the game... or reinstalling it
