I upgraded my iPad to IOS 5 and now when I try to read my purchased iBooks I get the following error message:
'This page contains the following errors:
error on line 1 at column 1: Document is empty error on line 1 at column 1: Encoding error
Below is a rendering of the page up to the first error.'
The rest of the page is blank and I cannot find a way to re-download them. Any advise would be very welcome.
