Error simulating Nios V/m Hello World in Aldec Riviera-Pro

I followed the instructions per the Nios V Processor Tutorial document (AN 985) but I am not getting the simulation to work in Aldec Riviera-Pro on my Windows 10 computer.

I added all the necessary simulation libraries per the 'rivierapro_setup.tcl' script and compiled all the necessary files. However, I am getting this error message below:

Error: ELBREAD_0081 niosv_top_intel_niosv_m_0.v (142): Design unit niosv_timer_msip instantiated in intel_niosv_m_0.niosv_top_intel_niosv_m_0 not found in searched libraries: intel_niosv_m_0, work, hart, rst_controller, irq_mapper, mm_interconnect_0, onchip_memory2_0, jtag_uart_0, altera_ver, lpm_ver, sgate_ver, altera_mf_ver, altera_lnsim_ver, cycloneive_ver.

Am I supposed to compile the "niosv_timer_msip.sv" file as well?

Per the "rivierapro_setup.tcl' script, it doesn't look like I am supposed to, and it doesn't look like I can anyway since it is in an encrypted file.

Any suggestions?

Thanks.
