Most of the books that I have bought from Connect have had several errors in them. I must say that the most annoying was
Under the Banner of Heaven by Jon Krakauer where clicking on a foot note would take you to the part of the book where the foot notes were located but clicking on "return to text" would take me back to some completely different page. Thank goodness for the history function with the joystick.
Another issue that I found funny was after reading
Slaughterhouse Five by Kurt Vonnegut the book said "We hope you enjoyed
Brave New World.
The latter was probably due to the publisher so I emailed them directly. I am not sure who would be to blame for the foot note issue. I think it is pretty poor to get such a shotty quality product when in some cases they are charging nearly as much for an electronic copy of a book as they are for the physical medium.
Bottom line is that you are not alone feeling frustration on this issue.
I would like to add that the real place you should vent is back to Sony so that they have the opportunity to fix the product or contact the publisher to fix it so that others don't have to deal with the same thing you are dealing with.
