USB-stick multitrack gives sound in finder but not in LPX

Recorded multitrack form a rehearsel on a trust-worthy usb-stick. Wav files. In Finder they all play and sound like they should. But when I drag and drop into my template in Logic Pro X, the audio tracks looks normal but there´s no sound, no signal, no nothing. It just plays but no nothing.

I´ve tripledchecked my Focusrite Saffiere is the chosen audio input/output. This worked earlier today but not now. What am I doing wrong here?

The memorystick - I´ve used it for a couple of months and has been great.
