I have the same issue, although I ordered directly from FAW. I ordered on Saturday, and when I went to register the plugin in my DAW, I got “not connected to the internet” issue. I checked my internet, just fine.
I checked the FAW site, and it had hard crashed (first the site was just an error page, then a stock wordpress page – it went through a few iterations before it came back up). After it finally came back up:
a) I didn’t have the serial number on my clipboard anymore
b) none of the emails I got had the serial number
c) the FAW site doesn’t recognize my email/password
d) the reset password link doesn’t recognize my email
So I’m guessing they had a database crash or had to reset. Whatever the case, I used their chat bot to request my account serial. I also sent email about the failure … I’ve heard crickets. I responded to an FAW thread on Facebook. Crickets. I’m giving this one last try before I file a paypal dispute.
