flappypenguin Posted November 15, 2014 Share Posted November 15, 2014 (edited) I found the problem!!! you need to downgrade your java I was using java 8 25. You need to use java 7 update 72 FIX: first, colse all your things that are using java such as minecraft and the technic launcher (press the x in the corner), uninstall your java. search control panel on your computer by clicking the windows button, in control panel go look under programs click uninstall a program and uninstall your current java version. After that, go to this link. http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html Scroll down to Java SE Runtime Environment 7u72 It has to be 72!!!!!!! click accept license agreement. under that, if you are using windows, install the windows x64 for a 64 bit version. Make sure you are installing the .exe one, not the .tar.gz one. After you are done installing that, launch your technic launcher and try to launch attack of the b team. please tell me if it worked and if i was any help.
