Uhm, without the tablet driver installed that would be the problem why you don't have pen pressure (the driver enables the pen pressure sensitivity, without it it's just a fancy mouse). Also, you can easily download the driver for your tablet on the Wacom website. Before this tablet I used an od Graphire 4. Got if from a friend, but she didn't have the installation CD anymore. But even for older tablets you can still get the driver on the Wacom website (it's actually the same driver as I use now for the Bamboo Fun).
