How to: Bypass grey play button on Perfect World / Arc Games? Like Swordsman Online?

Hey guys.

I have got a beta key for swordsman online https://www.arcgames.com/en/splash/swordsman, if you got it by receiving an e-mail or going to any website giveaway, just download the ARC program here: http://www.perfectworld.com/arc/download

Then, when the program is installed, go to top left icon on arc's window screen and select redeem a code, and enter your beta key.

I've had an error that didn't let me play, play button was grey and after introducing my beta key didn't start the download, so the answer is simple: Change the Arc program language by: Settings-Language, and put it to English.

After that, just re-enter your beta key by going again into redeem a code, and a new window for installation will appear.

Thank you guys!! Cya soon!!
