I am using MP 14 ver. and was able to use traj. command until a couple of months ago. Now I see the following message and even can't reinstall the traj. plug-in.
Please advise me.

. traj, multgroups(3) var1(D*) indep1(T*) model1(zip) order1(0 3 3) var2(S*) indep2(T*) model2(zip) order2(0 3 3) var3(L*) indep3(T*) model3(zip) order3
> (0 3 3) var4(B*) indep4(T*) model4(zip) order4(0 3 3)
command traj is unrecognized
