ME TOO.
I'm having the same issues as everyone else.. I've not done anything different but the earlier version of PHOTOSTAGE I had no problems with saving Image Overlays after going back into a saved file.
It's got to be something in the SOFTWARE PROGRAM itself. It's like Photostage is saying: You need to Make your VIDEO and only ONCE then SAVE...Can't save again.
I have PHOTOSTAGE PROFESSIONAL v.8.15.
Please can TECHNICAL SUPPORT please reply and help. I"M READY to BUY NEW SOFTWARE from andother PROVIDER...
