First, don't panic..... Next, I don't think reinstalling 1.7.2 will do
anything to help you now.
Most folks have started a Chat session with Adobe instead of a telephone
call, so maybe you should try that now.
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
Betty, I can't speak for what will happen on your KOBO ereader when you do
the reset. Generally, however, when you reset your ereader, all that
changes is the administrative data.
