I had the same issue and it is coming from your computer. The following actions are only available on Windows.
Open notepad in Administrator mode, then under File, Open, type at the Directory Bar %SystemRoot%/System32/drivers/etc/hosts
In this file, delete all the line containing the word mojang. Save it (be careful, this file has NO EXTENSION).
If you previously used illegal way to enter in the Minecraft world, then be sure that everything has been deleted from your computer.
@loqk, I think the page didn't load properly, so you have to reload the page and then change the language. I just tried and it is working properly now.
Next time, try to post your message in an appropriate ticket.
