WPA PSK Options not showing up

I have a Blitzz usb wireless adapter.

When I use it on my laptop, the WPA-PSK option is available.
When I use it on my desktop, only WEP is available.
Both systems are XP.
I have the same drivers installed on both systems.

Can anybody explain why the difference between the two systems?

Thanks...

XP Service Pack Level?

Is the desktop system XP SP2? WPA support was added to SP with the SP2
service pack.
