I don't know why it has stopped ~ maybe an incompatible Windows update.
Unless you really need the (few) extra features of 2.0, you'll be much better off on 1.7.2.
There are lots of bugs in ADE2.0. Try replacing ADE2.0 with the older but more reliable v1.7.2.
(You can have them both installed at once if you like.)
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
The forum software is sometimes corrupting the link above. There shouldn't be a blank in 'editio ns.html'. The following redirects to the same page: http://tinyurl.com/diged172
Thank you !!!
Back to normal with 1.7.2
Actually like page features better in old version. I'm reading on a 40" HD TV and double page, large font is perfect for my old eyes
