Sorry for the reply delayed due to the weekend.
Could you please tell us whether you have tried to reinstall the program on your computer to see whether it helps? Did you get the problem with a specific file or every file?
If it is with a specific file, would you mind providing the problematic file and the detailed settings for us to have a check?
Please feel free to contact us by submitting a ticket here:
Thanks a lot and have a nice day.
