Yes my problem started when I tried to download a new login screen. Well I did just that and then installed it then I had to reboot perfect so far. Now comes the moment of truth to see if the login screen will work nope nothing just a black screen no where to login in at. So I decided to reboot in safe mode I did that and it worked I logged in but I don't know how to reset the login screen or what file it would be stored in. I need to get it open I'm a student and my work is on my com and I can't get into it.
