Error: Counter too large! with \alph{cntr} and cntr>26

I need Alphabetic numeration of my chapters.

But if they are more than 26 LaTeX gives an error message.

How I can teach LaTeX to continue numbering as AA, AB, AC etc.?







I get the following error message:

LaTeX Error: Counter too large.
