So for example, you dont see the description like above(hover mouse over)? In this case, you may want to relog first then maybe reinstall. I had that issue once in phase 3 for items/abilities anything tooltip like you said & i just restarted. Oh, you may want to try 'run as administrator' although its not really necessary.
