Just signed up for rush. Can see projects but when I click on one nothing happens. Have uninstalled, reinstalled, rebooted. Set use as administrator. Really frustrating. Wasted all afternoon on this. Seemed like a great app for cross platform compatability but now I am furious. Can't find any way to get support form Adobe other than here. Will give it a day.
Otherwise there are loads of other apps I was trying out there... maybe they actually work!
