I am currently running the test_mc_mvp3_train_h.do file of Cappellari and Jenkins (2006) , Calculation of multivariate normal probabilities by simulation, with applications to maximum simulated likelihood estimation. However this message appears after running the ml maximize command: mvnp ml maxmize plugin not loaded : use the adoonly option. I am using Stata 14, 64 bit.

May I know how to solve this? I tried to uninstall and reinstall the mvnp package but the same problem persists. Also, read about the adoonly option but cannot figure it out on my own.
