What's the difference between Developer Tokens of Sandbox and Production?

Hi there,

I am trying to install Evernote plugin on my sublime. This is my first time to do this. When I try to get the token from the sublime menu: Preferences>Package Settings>Evernote>Reconfigure Authorization, it shows 

1. Update: the creation of developer tokens is temporarily disabled.

Then I tried the the other way from the link  http://dev.evernote.com/doc/articles/dev_tokens.php on the page. I found out I could get tokens from Sandbox but not production and I have no idea why the sandbox account is different from my origin account, that means I created a new account for sandbox.evernote.com. And the token I created from Sandbox doesn't work on my sublime text. Any one knows how to fix this? I saw two posts say to contact the tech but it's freaking hard to reach them if you are not a paying client.
