The Dragon Block C mod for Minecraft versions 1.5.2, 1.6.2, and 1.6.4 crashes the Minecraft Launcher/server jar file with every attempt of initialization. Every single crash report is the same. I experience the same issue with the JRMCore made to work with the mod. Below is the copy-and-pasted crash report recieved after trying to launch the mod on Minecraft version 1.6.2.




Any assistance as to what I need to do to fix this would be greatly appreciated. ^^

Alright. I decided to run Forge 1.6.4 instead of 1.6.2 on the Minecraft Launcher, with Dragon Block C Public Test v5 AND JRMCore installed. After attempting to run the game, as far as I could get was the MOJANG screen before receiving this crash report:

I'm sincerely confused as to what I'm supposed to do or what I'm doing wrong. This is how I installed and ran Dragon Block C in the past, however now it no longer works? It's very frustrating. Any further assistance would once again be greatly appreciated. ^^


EDIT: I resolved my own problem. I was extracting the contents of the ZIP file into the mods folder when instead I should have left it in the ZIP file and placed the latter in the mods file. Once doing so, Minecraft started up with the mod running properly. I first recieved a missingdef java error, but I fixed it by renaming the "Entity" folder "Entitys" within the Dragon Block C ZIP file.
