Ok, so my minecraft will not open! I've done every troubleshooting thing i could find, reinstalled java, downloaded older versions, ive watched every youtube video and even went to /b/ nothing could help. sO please help me fix it, it worked like last moth then i installed some mods and boom stopped working i deleted the bin folder downloaded another one and everything still nothing. the browser version works but is laggy as help for some reason it wont open with curse and neither will the screenshot so please help me.
I would try backing up your entire .minecraft folder and then deleting it. Running Minecraft.exe should create a fresh copy. I'd wager you've just got some weird files floating around.
As for what to do, I'd listen to Wircea.
