i can log in remotely to work to get it working for you one way or another.
but if it worked within the last few days there may be a very easy way to get it back
do a system restore to a time when it was working and it might just straighten everything out just like that. If it does not please just get back to me and we can trouble shoot further.
System restore instructions - windows 7 or 8 8.1
hold the windows logo key down and hit Rtype rstrui.exe in the run box that comes up and hit enter
select restore to an earlier date.
Under the "suggested restore" which is usually not old enough to help is a link for "OTHER RESTORE POINTS"click that if the suggested ones are not BEFORE THE PROBLEM STARTED
choose a date that is BEFORE you experienced the problem
hit ok / restore
the computer will start to shut down
a restoring settngs box will appear with a status bar
when it finishes your computer will restart with the same settings it had on the date you restored to. your data will not be affected.
It is not perfect. But it fixes a lot of things.
