I've got Bryce 5, bought it about 2 years ago (I think) and I've suddenly started having 'generic errors' crop up when I'm trying to save.  Whether images or materials, same thing.  Done a bit of searching for a patch or whatever today and not had any luck.

I can do the 'save image as' but I'm losing out on some cool materials I made this morning, as well as some good 'setups' for future work!

Help?
