Thanks for all the help, I found my error. It turns out that out of thousands of data points, one of the cells in the imported file I was using had no value, so Mathematica didn't really know what to do at that point. Simple error to fix, difficult one to find. ~Andrea andrea.knorr at engr.uconn.edu (Andrea) wrote in message news:<bllp1h$c11$1 at smc.vnet.net>... > Has anyone else had this problem with the new version?
