NTI 7 burning problem

After successfully using NTI 7, Dvdshrink, Anydvd for several years now on Vista, yesterday I noticed a new window in Shrink asking for target source files, etc. What changed was before I could put target as D:\Name, and now it says D:\NAME.iso So after shrinking, and going into NTI to burn, clicking on D:\ there is no file there. I have no idea what happened or why. The Anydvd tech told me to use Anydvd ripper, then shrink. I did that and it now will not shrink without getting the proverbial red line. In all my years of burning, I’ve never had that problem. In fact, no problems at all. Where are all my files going, and are they shrinking… ???
Thank you very much…
