### the error message \"Error in halofit\"

Recently I modified CosmoMC and add two new parameters in program. for simple we call them k_1 and k_2. frist I choose the prior ranges $k_1\in[-9,-7]$ and $k_2\in[0,1]$, there is no any error message. However when I choose the prior ranges $k_1\in[-12,-3]$ and $k_2\in[0,10]$, I get the error message "Error in halofit".

What reason cause this error? Maybe there are some unnecessary constraints appear when I amplify the new parameter prior?
