You guys have an issue with the LeptonX packages again. I created different types of projects and they all built except when I added the LeptonX theme. And to be honest, I'm really disapointed...I had a demo with a client today and I could not run it. I thought I had messed up some configuration. Customer was not happy, neither am I.
It was a permissions issue. I got it resolved.
