I did click on the skip add. I have been using mods since early beta I think I know how to download them by now.
Sorry LexManos I was just trying to help by giving some more information since I am getting the same looping code, I was not trying to hijack the thread. For now i am using the DW20 server with lots of stuff removed and that is working.
I have the same problem http://files.minecraftforge.net/ this is where i get the file i click
1.6.4-Recommended 9.11.1.965 1.6.4 11/21/2013 02:31:00 PM installer
it takes me here http://adf.ly/673885/http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.6.4-9.11.1.965/forge-1.6.4-9.11.1.965-installer.jar
and it downloads this http://app.webinspector.com/public/tasks/18125344#
i think this is the proper 1.6.4 file
(it also happens for 1.7.2 and vanilla so it might not be your end it might be mojang)
