Plate solve doesn’t work for me

I’ve loaded APM and UCAC 3, I’ve entered the focal length, and I’ve tried all the solve options (Astap, Plate solve2, ANVSR, ..). It never gets past step 3. It always shows an error and displays these messages: ‘Auto center attempt failed! Auto center validation frame solve failed’ Run time error ‘6’. Where’s the problem? (Trabajo con una focal de 2500 mm)

Apologies for the delay… I’ve been I’ll and am just not going through support.

PlateSolving requires very specific setup and most require very specific hint input in order to function properly. If you’d like to provide more information about your setup, solver and the image you are trying to solve we can try to help.
