you don't seem to be the type who played for years, considering how much eye rape the is.
but I guess you are new to the forums.
You are completely wrong about him being new to the forums and he has been playing for years if you check his ID.
First off I have a question, did you try to enable your key from another computer because by the sounds of it you did. That does not work because your key links to your IP last time I checked. If you have not it could be something with your internet because I ran into a problem close to this once. Try turning off your router and leave it off for maybe 10 minutes. Plug it back in and check to see if you are out of offline mode.
You could also be running into a firewall problem. Make sure your firewall is not blocking Blockland.exe or any file related to it.
Try those and if they don't work well... of course post back.
