How full is your hard drive?
Try saving your AE project with a new name and encoding that.
Try rendering to a production codec out of AE's renderer queue and then use the resulting file in the Adobe Media Encoder to make the MP4.
I'm cleaning my hard drive right now! And I will try both of your tips! I'll let you know if it helped
Ok, so I tried it, but After Effects crashes at the same time where AME crashes. So it has to do something with the video?
It's getting worse. Everytime I try to do anything with the video/beginning of the video, AE crashes. If I put my timeindicator on the beginning, crash. Trying to delete the video, crash...
Where did this video file come from?
Do today's updates to the Adobe software help?

I just stopped working on the project. It worked when I tried it again in another project!
