JDufile

I purchased and installed Ufile 2021 last week. No problems. I have been using Ufile for 15 years (or more). I went to launch it today, The launching Ufile logo comes up but the program doesn't launch. I tried in safe mode, no joy. There have been Microsoft updates since I installed the program but is that it? Frustrated. Never had problems, ever previously. Hope they fix this ASAP.
