Windows 7 Trying to flash my BIOS- error messages?

I'm trying to flash my BIOS to fix some random restart problems I've been having lately. I have a BIOSTAR Group A880GZ motherboard from American Megatrends Inc. When I try to run afuwin.exe and update my BIOS through the Flash Utility that they have available on their site, I get an error message stating "Error Loading Drivers." I have tried running the program as an administrator from several different locations to no avail as well and I am wondering if anybody else has had this problem? I am in the process of contacting their technical support but was wondering if anybody else had any solutions in the meantime.
