Comment on Digital Drawing Tutorial by nortagem

K, my brush window doesn't show my brush (in the brush preview) as a squiggly line with a pointy end like in step 5. It looks like a squiggly with a round end. Is it the driver for my tablet or the settings in photoshop? I don't have the CD for the tablet with me, I just plugged it into the usb port. I went to the brush window, then shape dynamics, then I used the pen pressure setting. There's a triangle caution sign on it. I have PS CS2. Help please?
