  Hard to answer without a reproducible example (it's only
possible to answer questions without such examples when the
errors are very common with very characteristic symptoms -- not
the case here).
   At the very least we need summary() and/or str() of your data.
  sessionInfo() wouldn't hurt either.
   Do you have NAs or negative values in your response variable?
  In general, lme questions should go to the r-sig-mixed-models
mailing list.
