• Use a pastbin service to post full logs.
• Uninstall Java 8 and install the latest Java 7 for your platform (32bit/64bit).
• Always provide the API URL (the URL you paste into the Launcher to add the pack) when requesting help for a custom modpack.

Caused by: java.lang.ArrayIndexOutOfBoundsException: 6990

• That block ID must be <= 4095.
