[XeTeX] Bidi, memoir and footnotes

[Arash Zeini]

Hello,

I am using Bidi v1.0.3 as part of a packaged TeXLive installation on a Debian 
unstable:
"XeTeX 3.1415926-2.2-0.9995.2 (TeX Live 2009/Debian) // kpathsea version 5.0.0 
// Copyright 2009 SIL International and Jonathan Kew."

I have a fairly complex master document to hold all the pieces of my thesis 
together. I use the memoir document class with ledmac and several layers of 
footnotes. Now, when I try to load the bidi package, I get the following error 
message: 

"! No room for a new \count .
\ch at ck ...\else \errmessage {No room for a new #3}
                                                  \fi 
l.149 \newfootnoteseries{E}"

The line in question in my master document is:

l.149: \newfootnoteseries{E}
l.150: \twocolumnfootstyle{E}
l.151: \renewcommand{\thefootnoteE}{\alph{footnoteE}}

Does anyone know how bidi affects the footnote series?

Thanks and best wishes,
Arash
