Minecraft Forums

I purchased Minecraft on Friday from the Minecraft site (1.8.1). With that download came the Minecraft Launcher (1.6). I then downloaded the latest Optifine. After that I downloaded the latest Java.



I cannot run Minecraft. I hit "Play" from the Launcher, it disappears, then I get an error "Java Exception". I have tried to fix this problem myself, but the forums are so chaotic that I just couldn't do it on my own.



SOOOOO......Help please! I even wrote Mojang for help, but they told me to use the Forums.



Here are the logs GAME OUTPUT and LAUNCHER LOG (both taken from the tabs of the Launcher).

sorry wrong section, this is for Unmodified Minecraft. optifine is a mod, post any crash logs in a spoiler as a reply in optifine's post.

besides the fact that you have mods installed, so are in the wrong section, a quick google shows that your error is related to the mod you have installed.
Which is why modded minecraft shouldn't post here.
