Need some help with PDAnet

If anyone is successfully using this, please lend me a hand.

I followed all the guides I could find, but still not having any luck. I downloaded pdanet on my iphone. Then I clicked on my airport icon on my MBP and created a network. When I did that, the icon turned to the one you see in the pic below. I selected my new network on my iPhone and started pdanet.

At first it connected successfully, but I still couldn't do any internet activity on my MBP and the airport icone didn't change. In pdanet it showed some activity, like 5,000/32, but that was it. After subsequent connections it was more like 5,000/0 (no activity on the right). And now I can't get it to connect at all. I tried creating a new connection on my MBP, but not having any luck at all.

Please let me know if there's something else I need to do, like adjust my network or sharing preferences.

Thanks for your help.

Do you have a good signal on your phone?

Yeah, I had a great signal.

I finally figured out what the problem was. I use an Airport Extreme wirelessly, but I also have to plug it in for bootcamp/WinXP because wireless doesn't work well for some reason. Well, I guess when I tried connecting wirelessly through my iPhone and was also wired to my Airport Extreme it was messing things up and I couldn't connect. Once I unplugged it ran just fine.

Long story short, it works and I am very happy. It's not the fastest connection in the world, but it'll get me by when I'm hanging out at the airport waiting for a flight or something.
