You said you used Galaxy 1 for a long while, but then you said games worked fine offline, so I assume you didn't use galaxy after all.
Then, you proceed saying that horizon was crashing (so, you were playing online after all?) and updated to Galaxy 2 then what?
Do you play through galaxy with internet ENABLED? Is internet enabled the first time you launch Galaxy? If not, try to close and restart galaxy (clicking X is not enough).
Achievements are not broken for HZD. Your config is.
Also, I get the feeling there is a very very simple step we are missing here. You did not respond to my suggestion to look into the firewall.
Have you bothered to read the whole thread? Did you already try/check this one?

EDIT: Now it works, finally! Don't know what did it in the end, but after un- and reinstalling galaxy, verifying game data (tried that before already) and giving Galaxy more rights in my Windows Firewall settings, achievements unlock now.
