Reconstruction never progresses.

Hi, I am having trouble generating a model in RC.
Alignment using XMP workflow worked well but when I hit ‘high Detail’ to generate the dense cloud the time goes up as if it is processing but the bar never moves. Also, the finish estimation is the exact time that the processing started and never changes.
Abort does not work, the only way to close down the application is to end task manually.
I have tried restarting my computer. Starting from scratch in a new scene. clearing cache etc and nothing seems to work.
The scan is of a head and is from 44 cameras. I have had success with other models but this one just refuses to work!
Any suggestions?
Thanks

Jules

Hi julesmalcomson

Can you make a screenshot and enable the CONsole view in the user interface, so that we can see in what stage it is showing or even stopping ?
