Has it ever worked on your computer? If so have you made any recent configuration changes or run some type of system optimizer recently?
You may want to also try running your computer in selective startup with all third party start-up items and services disabled to see if you experience the same behavior.
Version 1.7.2 is the answer to many problems with ADE 2.0.
ADE2.0 regularly seems to have problems with Sony and Nook devices (and some others too?); and with XP.
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.

Thank you, thank you! I have been fighting with version 2 since Sept. when I installed it, as it froze EVERY TIME I copied something to my Kobo. Why the %^&*& introduce a version that is only compatible with Kindles???? Now I have the 1.7.2, and everything works again.
Beither version is compatible with Kindles; but that is Amazon'c choice to lock Kindle users into their bookstore, not Adobne's choice.
But it would have been helpful if they had tested the new version before releasing it;
and done something about the huge number of bugs they have known about for over two years.
