I just installed ADE on my brand-new Windows 8 machine. Every single document I open, the same thing happens: the first page is displayed properly; then the second page comes up next; but then, each subsequent page is identical to the second page. If I scroll through the document, the page counter continues to tick up, but the page does not change. If I resize the window, however, the proper page will appear, but then all the subsequent pages will look like that new page. I was able to install ADE no problem on WIndows 8, but this problem happens for every single document I open.
I haven't seem this problem with ADE2.0, but it does seem a very creative program when it comes to getting things wrong.
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.
