At home I usually switch between mine and my friends router since internet tends to act screwy sometimes. One day, I got a notice on my launcher warning me about suspicious activity and telling me to change my account password. So, I did that while on my friends router. Come time when internet gets weird, I switch to mine, and the launcher fails the version check. I open my web browser and web pages load fine there, so its not like my internet doesn't work, the launcher is refusing to connect using my own internet, giving me enough reason to conclude Square Enix banned the IP address from accessing the game.

As far as thinking as to why Square would do that, I honestly can't recall a viable reason for this. It's not like my account is associated with RMT, and even if it was, wouldn't they ban the account instead of my IP? Or maybe they thought an unauthorized user has accessed my account, which seems more viable then the former, but banning IPs without getting a report for it first is like pouring a bucket of water on a stove that's not on fire.

Words cannot express how confused I am.
