I used the lumerical for a long time. Today it suddenly cannot open any files, I did not make any change. When I open the file from the lumerical, it just stucks at this page. Even though I restart the laptop or install the software again, this did not solve this problem. Could you know how to make the softward work again?

Try to remove the Lumerical product preference.ini files. Step #4 from this post. Otherwise, check your graphics/display drivers, this might have been updated by Windows updates. You might have to update it using the drivers from the manufacturer's website.
