No, everything is using Elite Server, and using Content Manager Server pages to setup Config files.

So, you have probably same problem as i had. There is some problem, like corrupter json file in one of your tracks inside the zip. So go inside the archive (total commander) and delete second half of tracks and then try reupload again. If problem persists, delete second half of actual content etc. You need to select that one (or maybe tow, three) track, with the problem and then repair it.
