How much is a licence FFT IP core, is it better to buy a full version of Quartus?

Dear madam or sir,

we using Quartus Prime Lite (about 2 years ago) and Intel Max10 FPGA. Now we want to use FFT IP (Installed IP-> Library-> DSP-> Transforms-> FFT). If I compile my project, Quartus say:

Error (204012): Can't generate netlist output files because the file "C:/Users...hyper_opt_OFF_pkg.vhd" is an OpenCore Plus time-limited file. Remove the unlicensed cores or obtain a license for those OpenCore Plus time-limited IP cores used in the design..

I want to do a simulation in ModelSim and I can not. I read the issue and my question is: How much is a licence FFT IP core, is it better to buy a full version of Quartus?

Sorry for my english..
