I'm going to murder my Wacom Bamboo Fun Tablet...?

This product comes with a bundle including Adobe Photoshop Elements 6.0 and Corel Painter Essentials 4. On neither can I figure out how to activate the pen pressure setting. I have ravaged the internet for a solution only to be thwarted at every angle. Can somebody PLEASE help or give me a screen shot at the setting or SOMETHING to help me with either of those programs concerning the pen pressure. I'm at the end of my rope and I'm desperate.
