A guess.  What does the new installation think your computer name is?
If you said yes to the laptop question it will be LOCALHOST.  Your old
data areas almost certainly same something else, e.g. ELSE.  To fix
this

cd $AIPS_ROOT/DA00
ln -s ELSE LOCALHOST
edit DADEVS.LIST and NETSP to make parallel entries for LOCALHOST_n as
                           are present of ELSE_n

cd $AIPS_ROOT/DATA
ln -s ELSE_1 LOCALHOST_1
ln -s ELSE_2 LOCALHOST_2
etc

(or if the data areas are actually elsewhere in the DADEVS.LIST make
those link files elsewhere)

The start up looks for data areas under the name by which it calls the
host - which is how we manage one DADEVS.LIST for > 100 computers.
