On my Mac with OS 10.12.6 Rig manager 3.0.100 shows me a startup error message "Cannot log into Rig exchange...."
It's been this way since version 3 and above (i ran all the betas before the elevated versions)
My user name and password works fine on the website, and they work fine on my windows 10-machine running rig manager of the same version.
I have tried changing the password.
Help?
