I'm not sure if this works but if you can't download the modpack or update it try downloading it from this link and put the folders in. If you are updating it you can open the modpack folder and delete the configs, chocolate, and mods folders and replace them with the new ones. If you don't have the modpack go to your .minecraft folder and replace configs, chocolate, and the mods folder. Make sure you install Optifine in the mods folder and install the lastest version of forge 1.6.4.
In addition to an extensive bestiary of aliens, giant insects, ogre reptiles, assistant girls and other creatures, a pet taming system has been added to the game. Each player will be able to envy himself a miniature monster that helps in battles. Adult monsters also do not walk around just like that. They are the guardians of dungeons and treasures. New ores and materials will allow you to craft incredibly huge weapons that are two to three times the height of the character. If you dream of fighting Godzilla on a dragon, then you should definitely download Ore Spawn - Monster Mod for Minecraft 1.7.10/1.6.4 and go hunting with giant creatures.
