I've been attempting to install forge for 1.7.10 on a clean windows 7 install with a brand new install of Java 64 bit, with no success. First when I installed the recommended 1.7.10 version of Forge I was getting the old scala libraries failed to download error that has been well documented here in this forum. So I followed Lex's advice in another post that suggested to use "-Djava.net.preferIPv4Stack=true" command when manually running the forge 1.7.10-10.13.0.1180.jar in a command prompt. To my stunned joy it worked, the scala libraries downloaded smoothly and it appeared that Forge installed correctly.
However, whenever I attempt to launch a single player world, minecraft crashes. Whenever I attempt to connect to a multi-player server the connection fails and MC keeps searching for a connection. When I run a clean install of MC I can connect to multi-player again, and obviously there's no crashing in single player with an unmodded installation. I wouldn't be shocked to learn this problem is because of something I've been doing incorrectly during the installation process. I have looked all over this forum including the EAQ's as well as several other sources to try and solve my problem with no luck. I attempted to install several other versions of Forge as well and I keep running into the same set of problems.
Can someone please take a look at the error log I am posting below and let me know the error of my ways?
