Save scene in PW

Hi all

I'm trying to save a modified scene in photoworks, but it wont let me. What happens is that I can see a dialogue box flashing for a micro second, but then nothing more. Same thing happens when attempting to save lightings.

Same thing on two different computers and two different versions of SW.

1. SW2008 64bit Sp 3.1
2. SW2008 32bit Sp 2.1

Any ideas about what can cause this?
