Hello, it’s me again!

We updated to windows 10 last month and since then it has been a nightmare.
LR and LM are no exception. Since then, I can’t see any animations and some files are reported like missing (mp4 files, I think).
Do you think this is related to the new Windows version?
Is there a way to solve this?
And… are there any updates coming soon for us who have been left with half-working LR - LM?
