Logic won't open because it say's core midi driver is missing
I've tried uninstalling it and re installing it to my computer and it still won't open. The loading window that pops up after clicking on the logic studio icon says checking midi drivers and it will stay there for around 30 minutes then logic will open. I am unable to even close logic once that occurs because a consistant reminder pop up window keeps me from clicking on anything.
Logic Pro, Mac OS X (10.7.5)
