Is it possible to find ID one used to initially to access ebooks? Have tried authorizing my computer, but in turn lost access to allready bougth products. Error code: "This computer needs to be authorized with a vendor ID to open *Title*. To start the authorization process with a vendor ID, click on the continue button."
When I enter Adobe ID, this appears: "The vendor account you entered is not associated with the item you are trying to open. Try again."
