logic coremidi issue after update

HI! I have just updated logic from 10.0.0 to 10.1.1 and after restarting my mac mini, now when i start logic the dialog (error initializing coremidi) comes up.

I already checked the audio/midi utility app and my keyboard (connected via usb) is detected and working with standalone apps like kontakt and other synths. It's just logic that won't work with midi. HELP!
