If you got your code from:
http://eqemulator.net/download.php
Then you should try downloading the latest available revision from:
http://code.google.com/p/projecteqemu/downloads/list
as that is where the current code is now posted. The spawnchance column was dropped from the traps table in Revision 104.
The server setup guides on the Wiki need updating to point to the GoogleCode SVN downloads.
