So I spent a bunch of time editing a video on WMM and I saved the project using the drop down menu by using the "save project" option. When I opened it later, it wouldn't play and the video clips that I edited have exclamation points with yellow triangles surrounding them. Is there any way to recover this video? Thank you for your wisdom!!

Save project saves the editing of the video so you can re open the edited video and again edit it with WMM. You still need the original video present in order to continue editing. If you want finish editing and apply the editing to the video so you can watch it you need to go to something like save video as, and WMM will render your video.
