lang004, lang005, lang006, lang011, and lang014 do not exist. A missing lang016.dll would not cause a crash; a missing lang016.dll would just cause the messages for Atlantean objects not to appear in ZT.
There are a number of causes for ZT to crash. The timing of the crash can often say what caused the problem. The "Causes of ZT crashes and how to avoid them" topic at DG can help pinpoint a problem: http://www.ztcdd.org/DG/index.php?topic=5452.0
But yes, it is also possible for ZT to crash if a critical ZT file is missing. The programs to list what are in folders and subfolders are already available here: http://www.ztcdd.org/DD/index.php?topic=10658.0
That link will provide us with info of what is in your ZT game
