First, perform a complete uninstall through the software of the drivers. Then, search for AARK*.* and delete any files in the c:\windows directory. Then, go to Start, Run, and type REGEDIT. Be careful not to change any settings but these or your Windows could be corrupted or even unbootable. Go to H_Key_Localmachine, Enum, PCI, and delete any folder starting with ven_1057 and reboot. This will force Windows to re-detect the Aardvark card upon reboot.
