That said your tip was useful, so thank you .
After doing it, I've noticed my launcher is set on North America by default. It shouldn't, I'm from EU and I'm supposed to have the EU client.
Also I've tried to switch language and it downloaded Eng_US...I don't know if they have Eng_UK (the name suggests they do) but if they do I should be dling that instead.
I wonder if I didn't end up with a US client somehow. Maybe I should redownload and reinstall. The fix probably isn't due for next hour, so I could try that. Seems too obvious but hey, you never know.
Hey, the client is set to NA by default, and when trying to connect with a EU account, it will switch the default to EU.
so no need to re install..
