I'm using this CV template and it was working fine in the past. But now the same file gives the following error:

package keyval error: bibtex8 undefined

I tried the following two different codes:

\usepackage[
        sorting=ynt
    , bibstyle=authoryear-comp
    , labelyear=false
    , defernumbers=true
    , maxnames=20
    , firstinits=true
    , uniquename=init
    , dashed=false
     ]{biblatex}

and

\usepackage[
    sorting=ynt
, bibstyle=authoryear-comp
, labelyear=false
, defernumbers=true
, maxnames=20
, firstinits=true
, uniquename=init
, dashed=false
, backend = bibtex8
 ]{biblatex}

Any help in this regard will be highly appreciated.

Have you tried with bibtex as the option for backend, and then run bibtex8 instead of bibtex? –  Guido Mar 17 '13 at 9:23

I get no errors. Please add a minimal working example (MWE) that illustrates your problem. Is your distribution up to date? –  Marco Daniel Mar 17 '13 at 9:28
    
Thanks @Guido for your comment. Can you explain your comment in detail? Thanks –  MYaseen208 Mar 17 '13 at 9:36

According to the biblatex manual biblatex does not know whether one runs bibtex or bibtex8. The differences between bibtex8 and bibtex (beside memory) are on sorting (mix-case sorting is allowed in bibtex8) and handling of non-ASCII characters. The other option is to check whether you distribution is up to date (and eventually you can have a go with biber). –  Guido Mar 17 '13 at 10:48
    
@MYaseen208 Can you add \listfiles to your input and see what the resulting File List in the log says? I wonder what version of biblatex you have installed. –  Joseph Wright Mar 17 '13 at 11:22

The problem is that you are giving

\usepackage[bibtex8]{biblatex}

instead of the required

\usepackage[backend=bibtex8]{biblatex}

as bibtex8 is a value for the backend key and not a key in its own right.

A full example which works fine for me:

\listfiles
\documentclass{article}
\usepackage[backend=bibtex8]{biblatex}
\begin{document}
\end{document}

and gives file list

Even using \usepackage[backend=bibtex8]{biblatex} throws the same error. –  MYaseen208 Mar 17 '13 at 12:07

@MYaseen208 Please try my MWE and compare your file list to mine, then report back. –  Joseph Wright Mar 17 '13 at 12:14
    
Every item my file list exactly matches with yours. Thanks a lot for your time and effort. –  MYaseen208 Mar 17 '13 at 12:22
    
@MYaseen208 In that case something odd is going on: can you e-mail me your .log file (joseph.wright@morningstar2.co.uk) –  Joseph Wright Mar 17 '13 at 12:23
