yesterday i just got this beta invite code and then downloaded the client, but when the log-in screen appeard, there was a message like 'servers are currently unavailable'
so i googled to solve the problem, found out that i have to click on the tab named 'beta management' in my account setting. but it turns out there was no such a button in 'my account' menu! i spared an hour to find out where it is, but couldn't find one. could someone teach me how to find the stupid button?
