I just received this error message when trying to setup my Digital Editions. I am about ready to throw this new Sony Reader out the window. Please help....
Whole error message below.
I have not been able to download from Sony...any suggestions on that. Adobe error (-474).
I've reset your activations. Usually when ADE keeps asking to activate on each launch it's a permissions problem writing to the registry.
Usually with cases like yours it's something preventing ADE from saving information to the registry:
1.) A permissions issue
2.) A registry cleaner
3.) An AV program preventing access.
Try this, launch ADE from the desktop shortcut (or go find the executable and double click on it), go through the activation process, quit ADE and relaunch. (This will prevent some problems with the browser launching ADE in low rights mode).
If this doesn't work you'll need to open up a support case at http://www.adobe.com/support/digitaleditions
Unfortunately, for you problem with the Sony software you'll have to deal with the Sony support, as Adobe won't be able to help you with that.
