I'd try the merge Peggy mentioned see if any happens. I don't want to say this but I think you need to off load all your Bryce stuff to disk, including that one, unistall Bryce and then reinstall with the patch...also do you defrag your disk once a month? When it's gets all wonkers and everything goes everywhere, because you delete this or that, sometimes Bryce forgets where parts of the files are stored. Disk maintainence is a must with 3d apps, they eat up so much space...can't hurt...
