It seems that there are some trial licenses and specifically there is a 120-day trial license for the AXI 1G/2.5G Ethernet Subsystem
With this design it is the only IP core that reports license problems.
That would make sense because the Spartan-7 does not have a hard Ethernet core (unlike Zynq series, for example), and the soft Ethernet cores are not supplied for free by Xilinx. If you're not goint to use Ethernet in your project, then it's not an issues. If you are, then the 120 days trial license could cover the project duration fine. But i DO understand the frustration with limited-time trial licenses 
. Especially since the (paid) IP core licenses are too expensive for individual/hobbyist use.
