I've bougth an ebook from America but get the following error when trying to download. "Error Getting License. License server communication problem. E_ADEPT_REQUEST_EXPIRED." I followed instruction on this error and changed my computer time and time zone to American time and time zone but now I get the following error "E_ADEPT_NO_TOKEN"
I've also added Adobe Digital Edition to the apps that are allowed through my Firewall.
