I am having trouble running this Example of a manuscript header with structured abstract which the journal of Astronomy and Astrophysics provides on their webpage. I have downloaded the "A&A LaTeX macro package" which they provide on their website, and put all files into the document folder.
When I copy-paste the above example into a tex-file, and try to typeset, I first get an error that there would be too many
}. After deleting the one which looks too much I get the error/message:
Class aa Warning: The running head built automatically from \author and \titlee xceeds the pagewidth, please supply a shorter form with \authorrunning and/or \titlerunning prior to \maketitle on input line 48.
I am not sure what that means, and I did not find anything relevant when googling for that error message. Any suggestions?
