EXS 24 Logic Sampler Users Group

Hi all,
Have searched the archives for answer 
to my question without luck.
Does anybody know if there is a way to 
convert .art files (articulation files 
for giga files) to exs format.
Have just bought 'Dan Dean Solo Strings' in
giga format. The conversion by the exs24
seemed to go well but the updates are
in .art file format which the exs does not recognise.
I would love to get the presets in these updates which
would be very useful.
Thanks in advance for any help.
George
