Can't put clips together

[computer2467]

This happens for whatever configuration or media I use and I do have ffmpeg, ffprobe, and imagemagick configured properly. After it says that every clip exists, it outputs this:
MediaException: MEDIA_UNAVAILABLE : C:\Users\<USER>\Downloads\YTPPLUSBETA1\temp\tempoutput.mp4 (The system cannot find the file specified) at javafx.scene.media.Media.<init>(Media.java:407) at ytpplusui.FXMLController$1.run(FXMLController.java:258)
and then stops with a blank preview screen and a full blue bar.

This happens to me aswell, I can almost create the video clip but ends with that error. I wish they would respond but YTP+ 2.0 should probably fix this. But I think I know the reason.

If your videos do not have spaces, please use FFprobe to see how the video was encoded and let me know. As of right now my node.js port has a UI and prevents users from rendering videos with spaces in them.
