Whenever I click play (1.8.7) it comes up with a Game Output and this is what it says:

It does that within a few seconds of pressing Play. Any suggestions on how to fix this? It seems to work on some of the 1.8 versions and previous versions (1.7, 1.6, etc.) only.

Firstly, navigate to your .minecraft folder. See this page for instructions if you're not sure how to do this: http://hopper.minecraft.net/help/finding-minecraft-data-folder/
Once there, delete the usercache.json file, then try running Minecraft again.
