Yup I see now, nothing on my PC indeed…
Probably because of this http://forums.coronalabs.com/topic/33101-corona-cloud-assets/.
They pulled the plug on the CC dashboard because it was not production ready. You can only get the assets if you are a pro subscriber and download an earlier daily build I think.
However the dashboard not being production ready it might not be the best idea to use it.
You should either wait or try to make a custom dashboard, sorry for the disappointment
Maybe the Corona guys can provide us with more information on this…
