Adobe epub 4.5.11 white screen

[kbzebrazzz]

I've been using Adobe epub reader for a few weeks and suddenly, when I open it I have a tool bar and white screen.  No library or anything else.  I have unauthorized and uninstalled, reinstalled and authorized a couple of times to no avail. I am using a very old (12 years) pc laptop.  I am old and basically computer illerate  - no kids or grandkids to help - which is my way of saying I appreciate any help but if you can keep it simple please that would be great.

Thank you!

delete the folder ...documents/My Degital Editions.

When you restart ADE this folder will be recreated. All the books will be gone, but should work. You might try copying the old folder on to a usb stick if you have books you can't redownload. If you move the old folder somewhere else (or rename) it might seem to be fixed but ADE will eventually find it and you might get a conflict.
