remove the 's' from https and the version number works fine. http :// www .realmofthemadgod. com/version.txt or just www .realmofthemadgod. com/version.txt
P.S. Previously, I tried to follow Ninjin's guide but wasn't able to update the XMLs. But the guide by toddddd https:// www .mpgh.net/forum/showthread. php?t=1211655 worked fine. So try that if the first doesn't work out for you.
