Windows 7 Asus A8n32 -SLI deluxe motherboard Gamemidiport issue

Windows 7 64 bit build 7000 i frequently get an action center message stating that there is an error with my gamemidiport and it refers me to get the update from asustek. I got the update and attempted to install it according to the directions given on the action center page but when i look for the device on the device manager list it is not there. The update is not self -install and i haven't been able to find a way to get windows to recognize it. How would i go about fixing this issue please? Motherboard is asus a8n32 -sli deluxe socket 939.
