@brandnguyen Indeed, the sub format must follow strict formatting rules in order to be recognized. You can find a sample of a supported sub file in the deploy/captionSamples folder.
Either way, even if the sub file is not corectly supported, that does not stop the player from working without it. From what you describe to me, the player does not load the settings.xml file altogether. This is usually caused by either not having a proper embed code, or because the player can’t find settings file at the designated location.
You can check that for yourself, or send me a link on private, I’ll have a look and tell you if I find an issue with the setting it live.
best regards
