Hello, how are you?

I updated the version of Twinmotion and the problem of my previous case (Number case 00531690) persists, I get the following message "AN ERROR OCCURRED DURING THE SECURITY COPY OF THE TWINMOTION FILE") and definitely does not let me save files with the extension .tm on my computer and I did everything you indicated. Please help me, I have tried everything.

I have lost a lot of progress and very valuable information.

Please I need guidance

Thank you very much
