Photometric calibration not working in 1.2.0 beta1

I’m sorry to write with my bad level of English… and from my little knowledge, I’m just starting with astrophotography and I love Siril, but since I use the Btea2 version I can’t do a photometric color calibration because it never recognizes the image and I always get give the message
There is no valid WCS information in the header. Let’s make a plate solving.
19:48:00: Using already downloaded star catalog
19:48:00: NOMAD catalog size: 2 objects
19:48:00: Findstar: processing for channel 1…
19:48:01: Plate resolution failed. The image cannot be aligned with the reference stars.
Even with images that I had achieved in other versions, and I’m using Andromeda and Orion…
I do not know what I do badly
Thank you

Only two objects (stars) are found in the catalogue. Check your focal and pixel size, they must be wrong.

Thnaks, thanks, thanks
That was the or my problem
