Couple tips. Ditch the software you installed on your computer when you first connected the dock, and don't use anything that auto-opens when you connect your camera.
Use the dock as a USB connection, and that's it. Once you connect it and switch the camera on the computer will recognize it as a storage device and you can simple drag the images from the camera, which will show in 'My Computer', into a file or something on your desktop.
Then, use a real photo editing software or a fast acting program like a re-sizer, to get the images how you want them for posting. Generally large images make viewing difficult online, so I always re-size the images to make them a bit smaller.
Once you have the folder full of images from your camera, you can very easily locate them and upload them to Photobucket.
