Default How to access as mass storage from TWRP?

I run windows 8, got this file: http://www.mediafire.com/download/4y...ile_Phones.exe but it doesn't seem to work. When I connect my phone from twrp I get 2 ghost drives on my computer that say "please insert a disk in drive E/F". When I put Mount on TWRP nothing happens.

Help please !
