One clip causing conforming freeze and crash in Elements 18

I am at the very end of a project, days worth of work, due tomorrow. I added one video clip that happened to be a GoPro 240 fps shot-different than the rest of content. Immediately this started causing hang-ups and in a panic, I saved to protect my work. But now that decision haunts me because whenever I open the project it starts trying to "conform" this one clip, and never moves past 2%. I cannot remove or delete the clips because it freezes or crashes if I try to do anything. I am ready to cry. CPU, Memory, and disk look fine in task manager, nothing over 34%. Please Help!!!
