Prior to launching TT, right click your program icon and select "properties".
This has worked so far for me...
In the properties box, select the "compatibility" tab.
On the compatibility tab CHECK the box next to "run this program in compatibility mode"
Checking this box will open a drop down menu. In the drop down menu select "Windows 7"
CHECK the box next to "run as administrator".
Then click "Apply"
Then click "OK"
Not sure why it let me so one tax filing and then stopped.
