Seestar Preprocessing execution error

Hello everybody.
I’ve been using this script for 3 months to preprocess photos taken with a Seestar. It has always worked fine, but on this last occasion I have an error message when starts the seqapplyreg command. Here I send you the log of that command to see if you can help me. Thank you very much.

Reason is given here. The reference images was excluded from the stack. You can change it and stack manually.

Thank you for the response.
I don’t know how to do this.
Could you give me a web address where I can learn about the commands used in this script so I can do it manually?
Thank you for your help.

I’m having the identical issue, and also need help understanding how to change the reference image and stack manually.
