I use ShadowDefender [http://www.shadowdefender.com/]
to test new programs and virtualize my OS on occasion as a security measure. Have done so for several years with both XP 32-bit and now 7
x64 without issue.
However, if I run virtualized, after reboot ME crashes and does not work any longer - even a new install is ineffective. When this happens I need to install a previous image from my backup, to have it working again.
To check that it is ME problem, I uninstalled ShadowDefender and installed Toolwiz Time Freeze [http://www.toolwiz.com/products/toolwiz-time-freeze/]
with the same result.
I am attaching the crash reports - and thanks for your work on this wonderful program!
