Problems since upgrading Intel (R) PRO/Wireless 2200BG Network Connection application

I have been having problems ever since upgrading my Intel (R) PRO/Wireless 2200BG Network Connection to the latest version (R107434.EXE) available on Dell's website.  Before the upgrade my Intel PROSet software worked fine.  Since upgrading my PROSet application states that there are "No supported wireless adapters available in the system."  Something else I've noticed is that while everything appears OK in device manager (i.e. "This device is working properly."), when I double-click on the wireless adapter I get a message stating that the "Adapter state not found in the registry."

I am able to use Windows to manage my wireless connections, but would like to get the Intel PROSet application working correctly.  Does anyone have any suggestions?
