If you were able to do this before, you've most probably lost you
environment variables.
You can try:
% echo $AMBERHOME
in your shell. If it returns nothing, that's the reason. You can add
AMBERHOME to your environment variables using
% export AMBERHOME=/usr/local/amber9 (or anywhere you installed
amber), if you're using bash
In the manual you can see more details.
