Hello!

My video project is 20 min long and consists of 210 parts.

It happened during editing, that somehow I still can see all

the thumbnails and the number of parts, but only 53 of them 

are playing, then it revinds to the first frame. All source

files are untouched, I suppose the .wlmp file is corrupt,

is there any way to diagnose and repair it? 

Thank you!
