[Firmware] Sansa Express 01.01.12 firmware released

Did you follow the directions in the 1st post of this thread? You have to move the StMp3Rec.sys file to your "C:\windows\system32\drivers" folder.

Note the instructions say you may have to try connecting (while holding the volume button) a few times before it works. You might also try switching your Windows to a Vista or XP (if possible) compatibility mode.
