Hi, We may not of received a replay as it may be that the newer premium version Flat UI is under non-free license terms? [1][2].
The older github version now states it's MIT and CC by 3.0 [3] (Category B) [4]. But fails to mention the non commercial bit :-( Justin 1. http://designmodo.com/flat/ 2. http://designmodo.com/license/ 3. https://github.com/designmodo/Flat-UI#copyright-and-license 4.http://www.apache.org/legal/resolved.html#category-b
