[Ifeffit] problem on opening data file

Hello All, Recently I found that I could not open my EXAFS data files using Athena any more. Previously I had no problem using Athena to do data analysis (the last time was in last year). Now when I try to open a data file, a small window appears saying this file 'could not be read by ifeffit as a data file'. This happened to both the old data files that could be opened previously and new ones that were obtained recently. All the raw data were taken on beamline X10C at NSLS in the format of .xfs. I appreciate it if someone could help and give me some suggestions. I've attached one of my data files as an example. Thank you so much, Ruoshuang
