I realize that some games do not allow you to chat if you're a lower level, but this isn't the case. Record of Lodoss War Online allows you to chat in all channel fields no matter the level.
I've done an experiment, I asked a friend of mine if I could log in on my account on their computer; their OS is Windows 7, I run Windows 10 Pro Version 1607. I could type in all channels just fine.
This leads me to believe, because the game itself was made with windows 7, it might be entirely possible that it just needs a script adjustment from one of the programmers.
