Flash that BIOS!

[dLUX]

When I try to flash the BIOS (in M-Flash screen) the directory shows the USB but the only file showing up is the SYSTEM VOLUME INFORMATION dated from whenever I format the USB. The BIOS screen is MSI although this particular rig was built by ABS. I've tried several different USB drives of different ages, from 8GB up which were all formatted to FAT32. I've tried formatting them to 4096 bytes as suggested in some forums. The file itself is correct and downloaded directly from MSI. I've tried various ways of getting the file into onto the USB like copy/paste, directly unzipping, etc. I will be trying ABS support directly tomorrow but one of you genius nerds may have an answer.

I've never had any problems flashing a BIOS so any help would be appreciated.
