CS4 Vanishing Point filter problem

[Kirk Gittings]

In the middle of working on a layered 16bit tiff image, after using the Vanishing Point filter successfully twice on this image, I now get an error at VP launch saying "the operation could not be completed". VP works fine subsequently on all other layered tiff images from the same shoot. It is just this one where VP no longer works.

1) Flattening the image does not help.
2) Resaving the image as a PSD, layered or flattened, does not help.
3) Rebooting the computer does not help.
4) Turning off GSL does not help.
5) Converting to 8 bit doesn't help.

I'm at a loss.....

This is on CS4 on a 64bit Vista Ultimate machine.

Any thoughts?

Ok if I copy and paste the image in a new window VP will work.

Which tells me what? Copying and pasting into a new window like that strips what from the image besides metadata?

Any thoughts?

Sounds as if something got corrupted, or that one of the layers is not rasterized.  What happens if you open the file and save it under another name?

Ok it just happened again on an image with no layers. So that is not the issue. Again it happened after doing a couple of successful VP procedures on the image. I will try renaming the file........nope that did not solve it.

Again it only worked by pasting the image into a clean new window.

When I get strange results, I trash the preferences file and things go well again.  To avoid unnecessarily redoing my preferences more than once, after I have redone the preferences I copy the new file to my desktop.  Then, if it gets corrupted again I just delete the old one and replace it with the one from the desktop.  Don't ask me what folder, though.  I have it written somewhere...
