If you are using pdfTeX version 1.0 the following piece of code in
protcode.tex causes the problem:

    \ifnum\pdftexversion > 13 
        \ifnum \expandafter`\pdftexrevision > `g
            \adjustprotcode#1
    \fi \fi

The check for \pdftexrevision fails.

Just add the lines:

    \ifnum\pdftexversion > 99 
            \adjustprotcode#1
    \fi

and it should work for the current and future versions.

Regards,
  Reinhard
