So you downloaded the tools and unzipped them. Then you dragged an image to the make pano (multires) droplet? If you do not have a license, be sure not to use any bat files that say swf. these require the license.
Have you moved any files out of that folder or are they all still in the unzipped folder.
I have seen those black boxes flash in the past, but not recently. In fact, I just did a quick test using the tools without my license and it worked fine for me.
already created pano
You mean an image right? a jpg or tif or psd
Edit: Did you see the black box actually processing something?
If so, go to your folder where the original image was and there should be new content.
