If you check the AFCAD supplied with KLAS with any editor, you'll see the ILS for 25L is both correctly positioned and perfectly aligned (269.94 deg True) with the runway, as you can see from the attached screenshot, the ILS is correct.
Also, note that this file was posted about 2.5 years ago, that AFCAD has been very likely already included in the main installer so, if you downloaded the full installer after April 27th 2009, chances are the AFCAD that comes with the scenery is better/newer than this one.
As a general rule, whenever we release fixes in the forum, we update the installer shortly thereafter, since we have a Trial version and, of course, it's best to include all the latest fixes in it.
