Filmpack 5 & 6 not saving modified files

All of a sudden I can’t save any modified images in Filmpack 5 or 6, standalone versions.
The programmes become non resposive and will crash (shut down). I’m using Windows 10 with FilmPack 6.17.0 and FilmPack 4.4.27 - both 64 bit versions.
Anyone else having this issue?

I rarely use FP standalone but I’ve just downloaded and installed FP6 6.17.0 (Build 66). I’ve only opened the one file and saved it but it works fine for me (Windows 10).

Paul, yes it’s strange, this used to work fine.
Sounds like I’ll have to raise a support ticket.
