I was having the same problem, but i've got a temporary fix...
So, you'll need a text editor like Sublime Me, Textwrangler or even textedit, and you'll need to go into the lux workflow folder..
I typed "find luxinate.py" into Alfred, and found the file. Open it up, then search for "def hasConnection(self):" and change "return False" to "return True" (line 827 of code)
It'll bypass its check, as i've tried changing the IP it pings to to something else with no result.
So it should help you out hopefully!!
