Thanks for the help LexManos but I have another problem. when I did the steps in the video, it said 'java' is not recognized as an internal or external command, operable program or batch file. Please help.
I downloaded minecraft forge installer for 1.6.2. and properly used the installer but instead of saying success, it said, These libraries failed to download. Try again. org.scala-lang:scala-library:2.10.2, org.scala-lang:scala-compiler:2.10.2. I did what the rules and EAQ told me to do but it still didn't work.
