Quartus Prime Lite IP Cores compiling

Hi, My name is Eloy Navarro, and I have a doubt about compiling with Quartus Prime.

The fact is that I was used to Ciclone III family with Quartus 10.1, having no problems to compile and program IP Cores with time limitation.

Now I have moved to Cyclone V and I'm unable to compile a project with IP Cores (FFT is the one I'm trying).

I am working with Quartus 15.1 Lite Edition and a BeMicro CV A9 as target board.

The user guide (ug_fft.pfd) tolds to manually add .qsys .qip and .sip.

Once attached, the compilation exits with errors ("can't generate netlist output files because "..." is an OpenCore Plus time-limited file." and "can't generate netlist output files because the encrypted file "..." is not available.")

I have not added anything else.

I don't know if these errors are related with something missing, licensing, libraries or maybe I'm doing all wrong in this new Quartus.

Thanks in advance and Best regards,

Eloy
