There are two possibilities here. Either the program is corrupted or a data file is.
we can try to figure out which one it is. either can be solved though if it is the data file it might be necessary to use a back up.
I can certainly call you and even log in remotely to fix it for you while you watch but there is an additional charge for that
what you might want to try first because it is very easy and can fix a multitude of possible causes is a system restore
System restore instructions - windows 7 8 10
hold the windows logo key and hit R
in the box that appears type
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 from the calendar that is BEFORE you experienced the problem
hit ok / restore
the computer will start to shut down
a restoring settings 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.
