I can't open .duf files
Hi, I'm Carlo Molinari, Italian user of Daz Studio for many years.
I updated my iMac to Catalina OSX 10.15.3, I reinstalled Daz Studio, but I have some problems:
I have an alert window at startup and I cannot open my .duf files, in gray, as in the attached images.
Can anyone help me please?

Catalina broke the general release version of DS. You need to use the beta version, which includes fixes for Catalina among other things.

Thanks. I must uninstall Daz Studio Pro, before install beta version?
No, it's installed next to the general release, you can have both at the same time.
It's run! Thanks!
