Now I get this error
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Every time I try and get an item from NEI it gives me an error in the chat saying that the ID:XXX doesn't exist. Also, when I try and get an item from the Creative Inventory it disappears when I try and place it on the ground.
