I have been rendering using rendercows for a few months now without any problems. Yesterday I ran windows update, updated Norton anti-virus, re-installed my rendercows, and now they have stopped working. When I render, it renders the first frame, and then Vue just shuts down. One of the times I tried it gave me a message that said something like: This application has requested an unusual termination. Please contact the software provider. So I am contacting E-on, but does anybody know what could be wrong. I have urgent work to do and can't afford to be stuck without my rendercows. The only rendercow that works is the one on the machine where Vue is installed, and on which I didn't run Windows update, which makes me think it is something to do with the windows update or the Norton anti-virus update. PS. I have tried re-installing the rendercows, resaving the Poser PZ3, different files, shorter animations.
