Sandboxie Support

I'm trying to open up Proxifier, in 2 sand andboxes, but Proxifier will only appear in one box, I have tried to reinstall sandboxie, and delete all files from the sandbox folder, but nothing helps, I am running the latest sandboxie.
Do anyone have any suggestions what I can do?

Hello Boffer,

I was able to launch 2 sessions of Proxifier using Win 10 + Sbie latest beta.
Have you tried creating a new sandbox with default settings?

Please provide more information so that we can assist :
