Can't acquire network address when WPA enabled

I am setting up a wireless network with a Belkin router, my Sony Vaio laptop
running Windows XP, my husband's Macbook, my iPod Touch and a Wifi radio.

I set up the network with no security settings enabled and all the devices
were able to connect to it without a problem. I then enabled MAC address
filtering - again no problems. I then enabled WPA encryption and the
Macbook, the iPod and the Wifi radio were still able to connect to the
network, but I now can't get my laptop to do so.

I select my network from the list of available networks and am prompted to
enter the WPA key. The computer then tells me to wait while it connects to
the network and says that it is acquiring a network address. After a minute
or so, this process times out and the computer just stops trying to connect.
If I disable encryption from the router, the laptop connects without
difficulty. I don't understand why enabling WPA prevents the laptop from
acquiring a network address and connecting. All the laptop settings are set
to acquire an IP address automatically. I know that I am entering the
correct WPA key because it works for my three other wireless devices. I know
that the laptop is WPA compatible because I had it running wirelessly on a
WPA encrypted network in my old house (albeit with a different router as I
was on cable broadband rather than ADSL then).

Please can anyone enlighten me?

Thanks in advance.

It usually takes me at least three shots to get he key correct. That has
happened when I had the laptop next to the desktop which was displaying the
key in the router.

Thanks for taking the trouble to reply, but believe me I've had more than 3
goes at entering the password. I cannot believe that in the scores of
attempts I've made, I haven't got the password right once. Even if I type
the password out so I can see it's correct and then paste it in, I'm still
getting this problem. Can connect fine when no encryption is enabled, as
soon as I enable encryption, the laptop can't acquire an IP address. All
other devices on the network can cope perfectly with the encryption. This
laptop has worked on an encrypted network before.

I didn't mean that the third time will be the charm. I meant that it took
me three tries before I got it right. It may take him many more times or
fewer times. In any case, it is quite hard to get the key set correctly.

There are 4 different WPA's

Make sure you choose one that all your devices can agree on

WPA-TKIP
WPA-AES
WPA2-TKIP
WPA2-AES
