Abstract Factory Vs Factory Method

I'm finding myself getting a bit muddled by these two patterns while reading DesignPatternsBook. Both classes have abstract classes (Abstract Factory, Abstract Product in Abstract Factory & Abstract Creator and Abstract Product in Factory Method). Both have subclasses that customize the classes for specific use - (Concrete Factory, Concrete Product, Concrete Creator, Concrete Product). So what's the difference between Factory and Creator? Both have specific subclasses for specific applications/...
