A Great Pumpkin Cheese Ball

It really wasn't firm enough to make into a ball, even after refrigorating overnight. Any ideas to make it firmer? The flavor is good, but I am concerned about how to firm it up with out changing the flavor profile!

I would recommend using grated sharp cheddar cheese rather than the cold pack. All the other ingredients will return to their naturally firm state, but cold pack spread is soft in its natural state.
