Lightswitch - Publish Greyed out in Configuration Manager

Question

I am attempting to publish my Migrated VS2012 -> VS2013 lightswitch application. I had to upgrade my project after 2012 decided that auto-generating my new tables code was just too hard for it.

2013 worked the charm, everything went back up and I continued development and I could continue to run the client (desktop) with no issues!

But now I've gone to publish for a client to do UAT on and I cannot publish. I hit publish and I get "This Item does not support previewing" down the bottom and nothing happens. My Configuration manager looks like this:

I cannot click on deploy.

and the migration log looks like:

Any help is greatly appreciated. Thanks in advance

UPDATE: I've also found my Output is showing: Build has been canceled.

Lightswitch 2012 was dead... Had to upgrade to 2013,this caused a heap of breaks, but eventually I got it publishing.
