Hi 

I have a new computer with Windows 10 and installed Windows Movie Maker 12 .I made a 15 minute movie with pictures and video and made frequent saves over a few days. I saved it as a movie to USB and played it on my TV to check. All was fine but I wanted to go back to project file to make some changes to some things. Any of the project files I open have several picture with the yellow caution sign on them. I have not moved any of these pictures. I installed a java update but other than that nothing has changed. I did a repair to Movie maker through uninstall / repair  and rebooted my computer but am at a complete loss how to correct this,

I would appreciate any help you can give me. 

Thanks
