Pro Tools 11..3 cannot import audio from any Non Mac formatted driv

So i just installed my PT11 HDX system and my first issue came up. It seems when i import or preview audio from any mac formatted external drive i am good to go, however when i try to import or preview through any external drive or flash that is non mac formatted such as "fat" format my session completely locks up. I have never had any issues importing audio since 5.1. Any ideas?
