WiFi USB Connector Issues

I hope this is in the right forum, it's kind of a software/hardware/networking/gaming problem

I recently bought a Wifi USB Connector so I can get my Nintendo DS online. It's supposed to work as an access point. Here's what I bought

Problem is it apparently only runs in Windows XP, but can run in Vista with some work. I'm running Windows 7 Home Premium, so I'm having some issues. The driver installs with no problem, it even shows some of the wireless connections that belong to my neighbors, so I know it's working. But I can't get the software to load that allows me to use the device as an access point. I've tried to use the compatibility software that Windows offers but it's not working.

When I try to use compatibility it tells me that XpSp2Fw.dll is missing. Don't know if that's an issue or not, because when I don't use compatibility that message doesn't appear, the program just doesn't try to load.

Any ideas on how I might be able to get this to run? Or should I just send it back?

Any help would be great as I'm kind of hit a brick wall.

Thanks
