Honestly, if I were you, I would really try and get ahold of MSI to figure out why you can't get their update tool to work; it would be the easiest method for you.
In the event that it just flat out won't work, what you need to do is to follow this guide step by step. Print it out so you can refer to it while flashing: How to Flash Your BIOS with Flash Drives
If you're uncomfortable, is there any way you can get your hands on a floppy drive and diskette?
