Can't retrieve sequence


I have been observing V4641 Sgr for some time, and using VPHOT to process the images. For the last two images I have obtained, when I try to apply the sequence to the image, nothing happens (target, comp and check stars are not identified on the image). Is there something I need to do to restore the sequence?
