[EDIT]
Ack! I'm so sorry, this was totally my fault. The main download file included an old, incompatible version of that module. I'm so sorry, I don't know how I missed it. I've just fixed it on the site.
To fix it on your installation, just download version 1.1.2 of the Classic Grey theme:
http://themes.formtools.org/classicgrey/
Then unzip it locally and overwrite the /themes/classic_grey folder with the contents of that zipfile.
Again, apologies!
