Hi Shaun.
you should use special edition license or your evaluation license is expired now. you could post the license here so we can know it clear.
anyway, the problem is that your project code size is more than the license allowed. you need update your license.
you can purchase license from here:

or you can apply an evaluation license. note: one customer can only apply evaluation license for twice at the most.
