about opencore and time-limited megafunction

hello everyone:

when i use programmer tool to download the file into board,the quartus view:

Info: SRAM Object File E:/MCU0.4/MCU_time_limited.sof contains time-limited megafunction that supports OpenCore Plus feature -- Vendor: 0x6AF7, Product: 0x00A2

is this mean that i didn't have permission to use some of megafunctions?

    See app note 320 for an explanation of OpenCore plus http://www.altera.com/literature/an/an320.pdf (http://www.altera.com/literature/an/an320.pdf)

    This message means that you have not purchased a licence for some of the megafunctions you have used in your design, so they will disable themselves after some time. The Nios II processor is one of these megafunctions.

    Most megafunctions will stay active if you keep the JTAG cable attached and keep the Quartus programmer window open after downloading the SOF. The exact details depend on which megafunctions you used, see the Quartus report window for details.
