just got my apps up and running. After logging on black screen appears with curser only so you need to do the following.
1..........press ctrl + alt + del
2..........click on task manager
3..........in task manager click on file drop box opens
4..........then click on new task when it opens
5..........type in msconfig in the open box
6..........click ok and system configuration box comes up
7..........click on tools a list opens
8..........click on restore reset to earlier date ( bottom of the list ) a box opens restore to this date, but
9..........you need to click on choose earlier date select the earliest date available
and that's it worked for me none of the fixes worked I tried most of them and got more and more frustrated
hope this works for you
