Deleting the position.bin and position.lrn can't hurt and might give you or
somebody else an idea to track the problem.

Deleting book.bin == deleting the book

Deleting book.lrn should have no effect whatsoever.

Deleting books.bin should make no sense as this file isn't changed at all during
play.

I think only Bob Hyatt can give a good answer to your question probably .

As I understand importing book.1 will not do anything good though as the
learning is stored in your book.bin anyway and book.lrn is just kind of a
logfile to what has happened in your book.bin while learning .

Position learning in Crafty should have very little positive effect on your
account's performance.

And yes - I don't have the slightest idea what causes your problems ;-)
