I didn't get the original reply, but it is far too vague to provide any *specific* guidance using SPSS. 

There are circumstances in which a mixed model can very closely resemble a time-series model based on the specified residual correlation structure. I am aware of some [unpublished] work that has been done in this area showing the similarities under some circumstances).

You've used "time series" and "repeated measures" to describe your data.  I'm
no expert on time series analysis, but I don't think those two terms are
synonymous.  Assuming it is really closer to "repeated measures", you might
want to take a look at "Applied Longitudinal Data Analysis", by Singer &
Willett (2003).  There is a companion page here that may also be helpful:
