Community AdminHi, the text string is correct, and it looks like you have taken the corect language swap steps.
Checking on your account, your game version has an "EN only" flag. It's worth checking if the store page where you purchased the game clarified this, and contact support for further investigation if needed.
Thank you for informing me, your answer was very useful in solving my problem.
When I purchased the game through Origin, I thought I had purchased the Worldwide version, rather than an English only version.
What ended up happening was I contacted support and got them to disable my English Only version of Titanfall and issue me a code for the Japanese version, which contains both English and Japanese languages. Once it is installed I should in theory be able to switch between the languages with ease by using the '-language ___' method; However I am unsure whether my save data from the other version of the game will carry over. I suspect not.
So if anyone finds my post via an irritated Google search, contact EA support and ask them to disable your current version of the game and issue you a key for a version with the correct language. You can do this via chat. Use IE to do this as the widget is broken in Chrome and you will wait forever.
Just be wary, it might wipe your unlocks so you'll have to do the campaign again and any of your Prestiges!
Unfortunately, the Worldwide version is bugged (I believe).
It includes the Japanese client VPK files, but trying to switch languages to Japanese fails (text/audio load in English).
The Worldwide version no longer lists Japanese as a supported language:
https://www.origin.com/en-us/store/buy/titanfall-ANW.html
"Supported Languages: Deutsch (DE), English (US), Español (ES), Français (FR), Italiano, 한국어, Polski, Русский язык, 中文（繁體）"
I was able to change Language to the ones in the above list, but not Japanese. Support told me it was a bug. I am going to ask if I can exchange my Worldwide key for a Japanese key, because all I need is Japanese + English.
Support tells me they are unable exchange my Worldwide key for a Japanese version key, and that my case has been escalated to Specialists as a result.
:S
