[Cant create a game server in remote windows server]

I am having this problem and have tried the above solutions. It seems to not accept my data center..... Please see error here http://screencast.com/t/YRZZkOrwWcmG

I have only one data center 1 and i've set my windows server to it but it still will not create when I use WHMCS but the game does create fine when I run it from TCADMIN. How can I troubleshoot this? or how can I see what the output from WHMCS is really sending to TCADMIN?

[Minecraft 1.8 download question]

I've changed the download link in tcadmin/settings/game and other/minecraft

to https://s3.amazonaws.com/Minecraft.Download/versions/1.8/minecraft_server.1.8.jar

to download 1.8 instead of the older version but when I create a new server it still doesn't install 1.8. Where do I need change this?

Thanks in advance for helping a newb
