Recently that I purchases a new computer and decided to install minecraft, I installed using the installer downloaded directly from minecraft.net website. Three days ago I was able to normally join a server. Now I noticed that the game after running the launcher has the LWJGL Icon (Picture).

When I started to see this icon, I would get "bad login" when running 1.6.4 forge mod loader, and "end of steam" when using minecraft vanilla 1.9.2. I have removed all mods and used a clean minecraft installation and clean %appdata%/.minecraft directory. I also have no sound.

Someone in minecraftforum.net did say that this might be caused by minecraft not being able to download resources (sound and the crafting table icon) from minecraft.net server, and this could be caused by cracked games or mods, but I am not using a cracked launcher nor mods, i do have paid minecraft.
