That is either not your console log or you only copied a part of it. We, meaning those who help, require all the console log.
There should be a popup window that shows what is going on in the launcher. If you do not see it go to the options tab in the launcher and check the box next to 'show console?' Now launch a pack and close it and the launcher, I'm not sure how to save the option any other way at the moment. The next time you open the launcher the window should appear. There will be a drop down menu that starts with minimal, select debug, if it is not already selected. Now try to launch the save. Once you get the crash change to the console window and click on the 'Paste my log to pastebin.com' button and post it. It should give you an url for you to paste here. If it does not then Select all the text in the console window and paste it into pastebin.com, post it and link it here.
