I just downloaded 'MLK DT Embankment Bridge' from the DLS. However, when I go into the game to use it, it isn't there. I've checked on the installed list (in CM) and it is there.
Quick update: I've now found the item in the game but it won't load - Just an empty viewing box and when you try to put it down in survayor nothing happens.
When you start TS2009, what build number are you showing in the lower right corner of the launcher? I have ts2009 build 44653 (service pack 4) and I just checked that bridge, works fine here.
Original, SP1, SP2, and SP3 all had the problem shown in post #2 along with a plethora of other problems. And of course once you patch to SP4 you might as well throw the whole mess overboard and get TS2010, for all practical purposes TS2010 is TS2009 Service Pack 5.
