Hi
New version at http://ftp.dlink.ru/pub/Wireless/DWA-120/Drivers/. I would uninstall your driver and install with newer version. If that does not work, uninstall. Extract the zip file to Desktop,open Winxp folder, plug in DWA-120, in Device manager choose update driver, browse to Desktop and point to .inf file, open. Windows will install the driver for you without D-link utility. Good luck.
