Hi Emerson,yup, I tried S29W068 to 071 and none of them worked; S29W072 was fine. You should report that finding to the website manager.Cheers, Holger

Thanks Holger.I've just sent an email to Tom Farr - from NASA/JPL - about the issue.

The corrupted ZIP files have been replaced by good ones.:-beerchug
