Custom Rendering

hi all,
I want to "create" a renderer for RS (2000). I read some articles on
this topic, and i found this technical sample for RS 2005 :
Display Your Data Your Way with Custom Renderers for Reporting Services
:
http://msdn.microsoft.com/msdnmag/issues/05/02/CustomRenderers/default.aspx
I've read int this newsgroup the way to implement the rendreing is the
same in RS 2000.
I can compile my customized renderer, but when i look at my reports, i
don't see my renderer in the ouputs dropdownlist... I have modified the
"RSReportServer.config" and "rssrvpolicy.config" files, as its written
in the article. I tried IISRESET, and I even restart the server, but no
changes.
Does this sample really work in RS 2000 ?
If yes, do you have any suggestion to resolve my problem ?I'm back to give more information about my problem.
Here's what i found in the report server log file (sorrry, some words
are French) :
w3wp!extensionfactory!ca0!06/07/2005-15:52:05:: e ERROR: Exception

.
It seems that my assembly mscorlib can't be called, or that mscorlib
can't access something.
I don't understand really this error. Can somebody help me ?
Thanks.
