There was a mistake in my earlier note, that I should correct:

   (Or you can estimate the interaction, and no degrees of freedom are
   left for either the time or time:group random effect).  All you  
can talk
   about is the average and the difference of the time effects for these
   two specific groups.

There is no problem with the time random effect; that can be estimated
from the within group variation in slopes, between subjects.
