Error 2002

[Sakkir]

What's annoying is that error 2002 has some significant meaning and since I don't really know what it MEANS, I don't get a hint about how to deal with the problem myself. This problem has come up before ( check "resolved threads" BTW mod, just because a topic has died down doesn't mean it is resolved). I've read that people can log in from different computers over the same network, but one computer won't be logging in properly. It sounds like the problem might be centered around specific consoles/computers in relation with the internet connection being used.

Edit: I redacted the question about the refund. Anyway, I solved my problem. But I did the steps too quickly to isolate the issue so I'll try to recreate it. I uninstalled Avast, which didn't change the outcome of attempting to log in. I also changed my firewall settings on the router. The fact that anything could be the problem, I then tried to Reset System Settings in the launcher. This worked.
Edit 2: So, it was two things. My routers firewall does not play nice with FFXIV anymore. Also, Resetting to Default is a good idea. I didn't get the client working until I tried both.
For other people the issues may be different so your mileage will vary.
