The VideoLAN Forums

Tried the fixed LUA script as well (Removed that line from hosts of course), it works. So, 2 solutions here.

Putting "92.240.234.122 api.opensubtitles.org" in the hosts (\Windows\System32\Drivers\etc\hosts) file did it for me.
Although I suppose it won't use opensubtitles.org to search for subtitles then.

Don't forget to remove it in the future.
