So all was fine was the launcher for a while, but just recently (probably about an hour ago) the launcher stopped working. Whenever I open it up, the button at the bottom just says "Play Offline" but is grayed out, never changing, even though I am connected to the internet. I checked the development console, and this is all that it said:

Launcher 1.0.6 (through bootstrap 4) started on windows...
System.getProperty('os.name') == 'Windows 7'
System.getProperty('os.version') == '6.1'
System.getProperty('os.arch') == 'amd64'
System.getProperty('java.version') == '1.7.0_21'
System.getProperty('java.vendor') == 'Oracle Corporation'

I just deleted my .minecraft and ran the launcher again. It worked fine.

Did you guys ever figure out what was wrong same things happening to me

Quote from Bacon_E1337

I don't see how not being able to play online is not being able to play at all.
Kids these days.

I've already said twice that I got it to work by deleting my .minecraft and running the launcher again, but I'll go ahead and add that to the OP.

Quote from Saliq

And I'm saying that you don't have to delete the .minecraft to fix this.

Quote from MasterKulon

No, you do. I obviously had already tried relogging, and it had done nothing. Unless you had the same problem and fixed it by relogging?
