Minecraft Forums

Hi, I play Minecraft on my Windows 8 laptop. I have all the requirements for it and it had worked perfectly until yesterday. When I press play it flashed the launcher on and off. The only thing that I can think of that's wrong is I gave it more RAM, but I changed it back before it broke. I reinstalled it and Java, but still nothing. The error message says

[15:51:37 ERROR]: Couldn't launch game

I don't know what's wrong but if you could help that would be great. Thanks!
