Issue when hitting record button for DI instruments
 

So my problem is that when I click record with a DI instrument, all that happens is an audible click is heard and the noise bar jumps up and stays stuck until I click the record button again. I'm running Pro Tools 10.3.2 with an Mbox 2.

I have a Macbook Pro OSX 10.8 with a 2.6 GHz Intel Core i7.

I also have 3.0 usb ports but in recommendation I got a 2.0 powered USB hub.

Has anyone else experienced something similar to this?
