Have you tried running it using lmer() in lme4 instead, see if that helps?

No, I don't think that will make any difference.
1) Post this to the r-sig-mixed-models list rather than here, as you
are likely to get a much better answer there.
2) Did you realize that treatment is a linear term in the fixed
effects portion, not a factor? If you don't understand the question,
Hi All,

trying to examine individuals interpersonal changes in the dependent variable
over time and how this varies between groups.
I am using the following code:
treat.lme1<-lme(DependentVariable~Treatment*I(Time-1),
3 matches
