Quartus 12.1 SP1: "m10k resources"

Hi,

I am using Quartus 12.1 SP1, cyclone V (5CEFA5U19I7N).

I have an error:

" Internal Error: Sub-system: U2B, File: /quartus/db/u2b/u2b_av_m10k_param.cpp, Line: 2018."

when I searched it, I found a similar problem with a fix but for Quartus II 13.0 DP2;

is there any fix/solution anyone is aware of? any advice?

Thank you,
