Help with WEC600N Adapter

My Compaq Presario V3015's Internal Wireless Adapter has died so I recently bought an Linksys Expresscard WEC600N to replace it. After installing the software (The Linksys monitor) everything on the program is grayed out except for "exit" which closes the program. After looking at device manager, the adapter isn't even listed their. For some reason, even when just plugging the adapter in after an uninstallation of the software and a restart of the computer, the device never gets detected even when it is clearly on (two blue lights for Power and Link/act). I've tried switching to Windows Wireless Zero connection but under network adapters, it doesn't even show a wireless option, just an LAN one.

It's an express card slot, so there is only one on my Presario. I've connected to an HP DV6000's express card slot and it automatically detects it and makes the plug in noise. My laptop however, despite Vista or XP will not detect the express card. I'm sure its not a Linksys and Compaq compatibility issue either as I've read other people using Belkin Express card Wireless adapaters and having identical problems as mine. At this point, I've given up googling up forums to get an answer as well as the tech support and speaking to a guy who can barely manage to understand English. I'm pretty sure its not so much a hardware issue as it is a software one. Everything works fine except for anything related to wireless capabilities on this laptop. Any help would be much appreciated.
