I am new to using Movie Maker. I am trying to work on projects that I have created and the timeline is showing yellow icons with exclamation points and other stuff. I may have moved the files around after saving them and/or renamed them. Based on some other questions I am seeing, does that create a problem? Are the projects now non-recoverable? Is there a way of getting them back? I don't recall reading about this in the overview, is there somewhere I can go to to find out about any other potential issues?
