Adobe Digital Editions 4.xxx

Dear readers,

I have ADE installed on my Windows computer but recently I got a new version of Windows 10 and ADE disappeared.

Today I installed ADE, had to fill in an authorisation for my Kobo reader, but the menu did not show Kobo. I continues with "continuations withaou authorisation. After that I put my new books in the ADE librabry from my online library. But when I connected my Kobo to ADE it gave the text: connect not allowd (or something). Kobo could not help me either. Adobe refused.

I uninstalled ADE and installed it 

Please help me. Wilma
