Hello, The last time I used the launcher was a few months ago. Today I wanted to play a modpack again but when I press play the launcher disappears and reappeares in the next moment without any game starting. I tried to reinstall the launcher and the modpacks. I also reinstalled Java 7 because Java 8 cant run the older modpacks, but it still doesnt work. Please help. Many greetings, Henrik techniclauncher_2017-03-12.log
