Logic Pro 9 Digi003 rack+ and logic pro 9 midi problems running on mountain lion


I have installed logic pro 9 on my my new Macbook pro laptop OS 10.8.5. I use digi003 rack for my interface. I already installed the latest Midi driver and core audio. its version 9 if I am not mistaken.

here's the list of things I have installed:

I also have a korg keyboard connected to the digi003 midi in. (this is my usual set up when I work on my Mac Pro tower which has a snow leopard OS ) with no problem at all.

Logic works fine on my Macbook pro. The only problem I am experiencing now is that whenever I play my korg keyboard, logic is not reading it, or it's not receiving any midi signal (you can see this in the midi activity indicator at the transport bar). But I can see the MIDI in blinking on my digi003 rack+.

Is there a way to solve or fix this?
