I already tried downloading by the laucher and the core, 2 times each, the launcher when completes the download, it says it had a problem with connection and need to download again, and the core, whenever I try to open on winrar it shoes an error and I cannot extract it, says its an unkown format, cant open on daemons tools too.
Just checked the download link myself.
It appears that the folder itself is not there, must have been edited a few hours ago. Will notify you once the download is up and running again.
