Please help me...i just logged into minecraft as i have been on this computer for almost a year when it happened. The start up screen loaded perfectly, everything was fine except the play button was all grey. and even though i have an account, obviously i do, the screen says "Welcome,guest! Please log in. Ready to play minecraft 1.7.10." Whats even weirder is that where the "log out" button should be, there was a button called "switch user" and when i click it, nothing happens. I cant hit play, log out, or basically do everything. Please refrain from comments like "oh just restart your minecraft and it should be fine" because if that were the case, idve fixed it already. Noone else seems to have this problem, i need help
Play button is greyed out, and nothing works...
