Mission hub, unable to load mission due to WASM error

I have looked around this forum and the bug tracker, but not found any topic matching my error. When I try to load a mission through the mission hub, I get a red warning saying "WASM Error - Package files have not been copied yet. Cannot start scenario". I have installed mission hub through contrail and it appears to be properly installed, as I can create a mission, but not load it? Any thoughts to what is causing this?
