Saw your post on RC. You are hooped with this error. You will need to send it in to Tunze to have the firmware reflashed. Had the same issue with mine when I first got it. I don't think the programmer put enough catches in his code if something should go wrong during the flashing procedure.
Following advice in older threads in this forum, I attempted to flash it in the avrootloader. I get this following error:
"Installed software version is higher as the update"
