Try Matlab. There is a number of different time-series packages available
for it. You can download trial version for free from Mathworks website.
Than get Econometrics Toolbox from http://www.spatial-econometrics.com/
and Time-Series toolbox from http://www.physik3.gwdg.de/tstool/

Besides, Matlab is very popular for scientific programming, you can only
benefit from learning it. It's much more flexible than "black-box"
packages like SAS, Stata, SPSS. In my opinion SAS is great when you need
to make comlicated manipulations with your data, but for statistical
analysis there are better alternatives.

Finally, if you do not want to spend too much time on learning a new
program, if you want something very user-friendly, easy to learn, simple
to use, then you have to get Eviews.
