Separate names with a comma.
The mojang server authentication servers are/were down, I had the same problem.
ohh. umm so what should I do now
like is there any way to solve the problem
I would just wait for Mojang to fix it, you can keep checking back at http://xpaw.ru/mcstatus/ for the status of all the servers, nothing you can do :p
ohh ok thanks alot
No problem :)
