I dowloaded Adobe Editions 4.5 for Windows, because I bought a first ebook for my Tolino ereader. Downloading worked fine, I created an Adobe ID and received an email with a link to verify my email address. So far so good. But when I tried opening my ebook in Adobe Editions, by clicking on it with my right mouse button, Adobe Editions opened, but also gave me the following error message: Downloading failed. Error with retrieving licence. Communication problem with licence server: E_ADAPT_REQUEST_EXPIRED. A chat with the support did not yield any results.
