I am using BibTeX 0.99d, I am not defining any other code for reference packages. All I use is:
\bibliographystyle{abbrv} %Define style here
\bibliography{myFile} %Reference to my bib file
It works perfectly, but its sorted by last name, and the journal requires by first name.
I gave a read to this, which is using another package, same case with this. Maybe I am missing something in my understanding of BibTeX vs Biber.
UPDATE (SOLUTION)
Thank you everyone, you were all right, there is no such a thing as order by First name, it was their mistake on the screenshot, I got confirmation already.
