I have recently gotten back into minecraft and wanted to try out a new modpack. I decided to try realm of mianite out. I downloaded it and hit play. The bar on the bottom of the launcher loaded a few times then the launcher closed and reopened. I decided it must have been the modpack so i tried out a few others. I tried attack of the b team and tekkit legends. I have the latest version of Java and my ram is set to 4gb. Vanilla minecraft works in the launcher and out of the launcher. I have tried everything I can think of but nothing worked. Is there any way to fix this? (BTW tekkit used to work on this same computer. There has been no OS updates on it.) pastebin: http://pastebin.com/51jdiNGZ (I tried some wierd things at the beginning but i have just uninstalled and reinstalled everything having to do with minecraft and technic(forge and java included)).
