Windows 7 Digitalpersona fingerprint reader not detected

[swsquadleadr327]

I just upgraded my HP laptop to windows 7 but now my Digitalpersona fingerprint reader says that it is not detected. I have the latest version of it, 4.1, but I can't quite figure out how to fix the problem. Is there some driver that I should try to install, or any other suggestions? I'd appreciate anything anyone might be able to suggest.
