Another user reported a similar problem, and it turned out that the "DATE-OBS" format in the FITS header was different from what is expected by AIJ. The expected format is "2013-01-27T00:39:54". If the format is something like "22/03/99", aperture photometry will hang and nothing happens when you attempt to do photometry. I have this as a high priority bug fix request, but it may be another week before I can provide a fix.

So that I can verify that this is your problem, can you post a copy of your FITS header?

If your DATE-OBS format doesn't match the above, for now you can completely remove the DATE-OBS entry from the headers of your FITS file and photometry should then work. You can do that by opening the image, then open the FITS header editor ,  and then highlight the DATE-OBS line with the mouse, click the "DELETE" button, and then the "SAVE FILE" button as shown in the screen grab below. NOTE: be sure to do a SAVE FILE rather than a SAVE which just saves the new header to AIJ memory, but not to disk.
