After in installed bluestacks and ADE in that android emulation too, the ADE doesn´t work on my Windows 10 system any more. Even when I´am deinstalling ADE in the android emulation of bluestacks und bluestacks itself. The new installation of ADE on Windows 10 doesn´t help too. Have somebody an Idea, what can I do? When I try to open ADE I see for a short time the hourglass and no error message or something else. Before the new installation I also renamed the Folder "My Digital Editions" in MyDocuments.
