Splitting Failure

Hello,

I am in the middle of putting together a larger size movie in movie maker (I re-downloaded the most recent program last week). I have been encountering several issues/glitches.

In splitting scenes together, some of the project videos turn green, especially after splicing several scenes together. This is very frustrating as you then can no longer see what you are doing.

Another problem, which is prompting me to post this is that I am actually unable to clip my video. I hit the split button, and it ends the video. I have many sound effects and narrations in this project. Earlier today I even had an issue where I split the video, and everything disappeared.

Hopefully you can help me here

Thanks
