This works for me:

cd "C:\Documents and Settings\Scott_2\Desktop\foo"
shp2dta using  s_01au07, database(usdb) coordinates(uscoord) genid(id) replace
use stats,clear
merge scode using trans, sort unique
tab _m
drop _merge
merge id using usdb, sort unique
drop if _merge!=3
tmap choropleth pop1990 if NAME!="Alaska" & NAME!="Hawaii",  id(id)
map(uscoord.dta) palette(Blues)

1.  Do you have version 2 of tmap.  The boundary file format changed
slightly from version 1 to 2.

2.  You will need to add the option -cmiss(n)- to where tmap calls
-twoway area- .  About line 540.

3.  -tmap- was replaced by -spmap-.
