My prosess of auto updating was failed once.
Then tried it again, luckly I was sucseeded in auto update!
But I've heard my friend failed twice, gave it up and downloaded new client from Oberin.com manualy :/
(He says it's newest version, sams as mine)
Well, and now I just found "Download" and "Download Oberin" section doesn't have contents atm. Maybe under construction?
If you mean the date next to the file, that was my mistake. I forgot to update that since April. But each time I've updated Oberin those files are always the latest version.
