How can I re-activate eBooks in Adobe Digital Editions after changing the mother board of my MacBookPro?

Question

After changing the mother board of my MacBookPro to fix the video display issue, all my previous eBooks in Adobe Digital Editions cannot be activated. The error message: "Activation Server error - code E_ADEPT_INTERNAL". Please advise what I can do to read my eBooks again?

Answer 1

Hmm, it shouldn't be that much of a problem. I searched my entire drive for "digital editions", and this is the whole thing:
/Applications/Adobe Digital Editions 3.0.app
/Users/user/Library/Caches/com.adobe.adobedigitaleditions.app
/Users/user/Documents/Digital Editions
/Users/user/Library/Preferences/com.adobe.adobedigitaleditions.app.plist
/private/var/db/receipts/com.adobe.adobedigitaleditions.app.bom
/private/var/db/receipts/com.adobe.adobedigitaleditions.app.plist
/Library/Preferences/com.adobe.DigitalEditions.plist
The application itself, three small files scattered in your user account, to unimportant installation receipt files, and another preference file in the root Library folder. Removing those should remove everything related to version 3, which is what I have installed.
Where I substituted "user" above (for the three entries of /Users/user/...), replace that with whatever the actual name of your user account is.
Edit: I double checked the installer using a small app that sorts out every file in an installer, and where each item would normally be installed. The main app is literally the only item in the installer. The receipts are created by the OS per the installer's data, and the other minor preference files are created when the app is first run. There is nothing else.
