Can't update BIOS

I have an MSI TOMAHAWK AC

When I first booted my new build up, the BIOS was so buggy, I barely managed to make my USB the boot device. The screen wasn't updating so every time I went to a new section on the BIOS remnants of the old section remained.

That serious of a bug hasn't happened again, but I still see the odd bug or 2, again minor remnants of the previous screen in BIOS.

I try to update my BIOS from the MSI website, I go to services for my motherboard and download the latest BIOS update and it downloads in ZIP file format.

I unzip using WinZip and there's just a .txt and a .190 file. No way to update BIOS.

Why is this? I've tried using earlier versions of the BIOS updates but same result.
