In this case, check if performing System Restore helps. System Restore will take back your system to a point in time when the application was working fine. While doing this, make sure that you select correct restore point. To know how to perform System Restore, refer to the section "Restore your PC to an earlier point in time" section on the link below:

If the issue still persists, you may have to follow the guidelines given by the technical team of the respective organization.
Hope this will help you.
