VSDC Videos runs accelerated when worked on Active presenter

Hi all,
i usually work on vsdc to prepare videos for further workings with A.P.
After a recent update, every video created with VSDC can not be used in A.P: they runs faster than the original (audio is ok) and any montage is foreclosed.
Does anybody suggest solutions?
Thank you all

Hi Claudio,

Can you please share a short video which has this problem so we can check?
