Re tested you software, it’s now working for me as well and it’s really fast ! I love the simplicity 
For my personal usage, the 2 things that would make its use faster would be :
- Projection method accessible directly from the main window (having other settings hidden in 2 levels of menu is OK but projection method is something I’m experimenting with every time I’m stitching)
- Drag’n’Drop to add files
Your application is just refreshingly simple compared to Hugin when you just have to stitch without mask or different exposition problems or other tricky situations that require special intervention, I’m switching to it right away
