Ok, guys. Problem!
The Link from support, leading to key activate, leads to a EA account, but in the activating key title there is nothing. At all.
If I remember correctly.
1. You need an EA account to activate, so you must create one if you don't already have one.
2. The keys are in your game library. You must click on the game in your library in the web interface. They do not appear in the GOG Galaxy interface. Click on the game in your library, click on more, select serial keys from the drop down menu.
3. Enter those keys in your EA account.
4. When you start up spore, enter your EA account name and password.
But, the keys and EA account is only for accessing the on-line content. If you don't care about the on-line content, you don't need to do this.
