I am trying to reload a book already purchased. It looks like if I click on it it will charge me again?

As long as you are using the same iTunes account it will not charge you again; but with books be very careful. There is often more than one version of the title in the store.

Instead of just searching for it, go to the Purchased tab at the bottom of the iBook Store and find it there. Much safer.

Thanks

No problem. Did you get it working?

Yes
