Both the SMP and GPU clients expired as of midnight. You'll need to download new versions from the usual places.
Fixes for the GPU client:
-- Later expiry (Feb 1st)
-- Allows X16xx, X18xx, X19xx cards & All In Wonder.
Fixes for the SMP client:
-- Later expiry (Feb 1st)
-- The localhost IP address is now hardcoded.
-- The client will force upload of results packets >5 MB (some results packets >>100 MB may still not upload)
These are, or will soon be, on the download pages.
I also note that most of the ATI X1xxx series is now supported. I bet it still won't work with AGP though (I have an X1800 that I could shove in and use, but it's AGP).
