Default Something's going wrong. Can anyone suggest what it is?

Hi

Something's going wrong here, but I can't figure it out. Does anyone have any suggestions? If you need more info, just ask.

Code:

Just a wild guess but you might have left over files laying around from a previous factoring attempt. Delete the files and start afresh.

I tried that, and it works.

I think I know what went wrong: when I was deleting the files, one ore more was held open by yafu-x64, but as far as I was aware yafu-x64 was not running. Eventually I found somewhere in the Win10 Task Manager that showed these files as open and which gave me the chance to close them, and I was then able to delete them.
