IRAF not recognizing SBIG .FIT images

Hello all,
I currently have a data set in .FIT format taken using an SBIG ST-L-1001E CCD camera and am trying to reduce it using IRAF. However, when I try to get IRAF to handle the files, it gives me errors. For example:
Although the file exists in the current working directory, IRAF doesn't recognize it as an image. When I try an 'imcopy' I get the same message, and when I open the image using ds9's GUI (which works), doing an 'imexam' causes the whole ds9 to crash and IRAF returns a number of errors.
Has anyone else out there experienced any problems handling SBIG's .FIT files with IRAF? Any thoughts on what might be preventing IRAF from recognizing the files as valid FITS images?

Never mind. I realized that the "imextn" arguments in the login.cl file are case sensitive. Adding "FIT" to that fixed the issue.
