I would recommend to perform a full reinstallation regarding the drivers and the software. You can use Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
Once you finish with the uninstall part, reboot the PC and then use the setup package and reinstall the drivers. I would check the Device Manager as well. Press Windows +R and type devmgmt.msc. Make sure that the device is not connected to PC.
