Quartus Ethernet module University license

Since last week I realized that Quartus 15.0 can’t compile successfully any project anymore, even I download one example.

https://fpgacloud.intel.com/devstore/platform/15.0.0/Standard/nios-ii-simple-socket-server-ethernet-example/

I got time-limited SOF file.

Do anybody knows what is wrong?

Below is the license list of my pc. Does “Protocol IP Bundle – University” cause the problem? If yes, how to fix that?

Product Maintenance Expiration

Protocol IP Bundle - University 11/30/2019

Quartus II SE Fixed for University Program 06/30/2024

University License NIOS II Soft Processor FPGA IP 06/30/2024

Also two typical errors:

Error (204012): Can't generate netlist output files because the file "C:/…./qsys/synthesis/submodules/altera_eth_tse_mac.v" is an OpenCore Plus time-limited file

Error (204009): Can't generate netlist output files because the license for encrypted file "C:/…../qsys/synthesis/submodules/altera_tse_top_w_fifo.v" is not available
