first of all, I really like simple interface of MEESC. I really like this product. 

But what really annoying me, is whenever I record my video with MEESC some video I recorded and preview works fine. But some video I recorded and try to preview it. It will throw and error. like this.  

"Cannot preview video. Preview window will be closed. Please try to import the video using Expression Encoder." 

And if I try to open the video in Expression Encoder there also it will show status as "Corrupt File" .

Please, some suggestions I really need some help. 

I am using:

Microsoft Expression Encoder Screen Capture 4 SP2

Window 10 OS.
