I have a problem when I run computer file,when the processor starts i find this writ:
"Unable to apply the next load step. Analysis terminated.
why?

Hi mhajirafie. I think if you perform a forum search on the phrase:

unable to apply

that you will receive a multitude of matches. This is generally a very good place to begin when trying to pinpoint the source of an error message.

I wish you well in your work. Best regards.
