Is there a WPA expert in the house?

I can’t get my (new) Hawking PCI network adaptor to work with it. I’m using WPA-PSK, and I want to use a robust pass phrase, and I do in my D-Link DI-524 router (34 characters), but when I enter it into the client, it lops off everything after the first eight characters. And even when I shorten the phrase to eight characters on the router to get it to match, it still doesn’t work. The options that I have on the PCI adaptor are WPA2 and “Any WPA,” and I have the same problem with both of them. I’d really like to get a wireless network going here, but I don’t trust WEP. (Note, it works fine unencrypted.)

Does anyone have any thoughts?
