I am trying to estimate a markov model using a single three category variable measured at 6 time points. get the following error for every indicator for every response pattern:

* THRESHOLD 2 OF CLASS INDICATOR PI2 FOR PATTERN 1 1 1 1 1 1
...

As well as an error regarding the standard errors and a problem of non-identification.I constrained the indicator thresholds to be the same across time points. Here are the relevant parts of the model:
%OVERALL%
[c1#1] (a1);
[c1#2] (a2);
.....
[c6#1] (a1);
[c6#2] (a2);

c6#1 on c5#1 (b11); !Homogenous transitions
c6#2 on c5#1 (b21);
c6#1 on c5#2 (b12);
c6#2 on c5#2 (b22);
....
c2#1 on c1#1 (b11);
c2#2 on c1#1 (b21);
c2#1 on c1#2 (b12);
c2#2 on c1#2 (b22);

model c1:
%c1#1%
[pi1$1*1](a);
[pi1$2*2](b);

%c1#2%
[pi1$1*-2](c);
[pi1$2*2](d); !Ind

%c1#3%
[pi1$1*-2](e);
[pi1$2*-1](f); !Rep

model c2:
%c2#1%
[pi1$1*1](a);
[pi1$2*2](b);


....
Any thoughts on what I might be doing incorrectly?
Thanks,
Chris
