We upgraded the server used for upgrade downloads and we are having an issue with the subdomain km.necromanthus.com that has been used for upgrades to KoolMoves. I will announce when the problem is resolved.

Edit: KoolMoves upgrade downloads are working again but KoolShow upgrade downloads aren't. I will report when that problem is resolved. The server upgrade entailed a major PHP upgrade which is causing these issues.

Edit: The issue with KoolShow upgrade downloads has been fixed.
