Yes, i downloaded the e-book again from googlebookstore but can't find the e-book on my tablet. Also when i download an e-book from another store i get in Adobe digital editions the error below:

For E_ACT_NOT_READY should you deauthoirze digital edition over the settings and authorize new.

If the download of the shop not work. I can not right help. Has you check if work with other internet browser?
