[DAS] trouble attaching das source

[Sean O'Keeffe]

Hi there,
I'm a bioinformatics researcher at the GSF national research institute 
in munich, germany.
I have set-up a das server (dazzle 0.97a) according to instructions on 
the ensembl site.
It seems fine and shows up all the data-sources when I point to the das 
server.
My problem arises when i try to attach the server to the ensembl web 
site - click on 'manage sources' on the das sources tab in contig view. 
Nothing happens when i type in our server 'andromeda.gsf.de:7070' and 
click on "show sources" - after about 5-10 seconds it just refreshes and 
is blank.
I had it running fine on a previous ensembl version but this is now 
version 20 and we've added extra data here also.
My dazzle config xml file (part of it) is below:
Any help would be great.
Thanks, Sean.

<?xml version="1.0" ?>
