We identified an error in our mirror of the QWI R2010Q3 files. We are correcting it. You will need to download any files you may have downloaded since October 1, or re-run any programs on the SSG that you may have run before the all-clear message. Sorry for the inconvenience.
Fixed. See http://www.vrdc.cornell.edu/news/error-in-the-distributed-r2010q3-qwi-files/
