Minecraft Dbc crash.

[IzzyTheKid]

Hey, I have been trying to use other forum posts to diagnose my problem. But i figured I’d just make one of my own. Whenever I run dragon block c, java 7 installed. I hit play on minecraft, it starts too load up. As if it’s gonna work. Then, all the processes of Java and minecraft just stop, and crash. Here is the crash report.

Any help would be amazing. Dragon Block C is one of my favorite mods, I’d hate too not be able too play it.

You need to allocate Java 7 to your Minecraft profile instead of Java 8.
