Adobe Master Collection Deactivating

Okay, so somehow my Adobe CS5 Master Collection deactivated, though I don’t know how. It deactivated and everytime I try to enter a new serial, I get the checkmark, but it says the product is “Adobe Master Collection CS5 Subscription Edition”. Huh? It won’t let me activate my software without adding my Adobe ID. I do have one, but it fails when I enter my ID, so I can’t use it.

I do have the activation servers added to my Hosts file. Am I missing something?
127.0.0.1 activate.adobe.com
127.0.0.1 practivate.adobe.com
127.0.0.1 ereg.adobe.com
127.0.0.1 activate.wip3.adobe.com
127.0.0.1 wip3.adobe.com
127.0.0.1 3dns-3.adobe.com
127.0.0.1 3dns-2.adobe.com
127.0.0.1 adobe-dns.adobe.com
127.0.0.1 adobe-dns-2.adobe.com
127.0.0.1 adobe-dns-3.adobe.com
127.0.0.1 ereg.wip3.adobe.com
127.0.0.1 activate-sea.adobe.com
127.0.0.1 wwis-dubc1-vip60.adobe.com
127.0.0.1 activate-sjc0.adobe.com

I have been using the Core Keygen for the serials. Did Adobe block these serials?
Answer #1
You can install it as a trial, and skip activation.
Add that stuff to your HOSTS,
then copy over the antilib.dll and acrobat.dll as per the instructions – it works fine, and updates no problems, I have used this method at least 20 times.
