If KOBO is not visible in ADE then try hard resetting KOBO.
Also try installing the latest verision of ADE 2.0 from adobe.com.

Re: Re setting Authorization on ADE
My friend is coming to help me with my problem. One question I want to ask is will the books I have paid for on Kobo disappear when I reset Kobo. I have 20 books on my ereader and 23 books in my library. Three of them I can’t get onto my Kobo Touch book. I hope they won’t disappear. I will let you know what happens
