I've made several adventures for Descent, but it's been a while. I just made a new one, and I can't recall how to properly save it. Something to do with "outputting the campaign" option. Does anyone remember how to do this? I keep getting the ".pdf already exists" message.

You have to give the file a new name (in the saving dialog) before saving - or overwrite the existing one. Export campain should be correct.

Thanks...got it figured.
