Problem solved.
Looks like the version comparability caused the problem. The version of libmySQL.dll need to be old enough to work with djuggler. I use the one downloaded form here,
http://downloads.mysql.com/archives...hp&v=5.2.1 You need to copy libmySQL.dll to the djuggler install folder if the computer is running an non-compatible version of MySQL server, or not running any MySQL server at all.
Now, at least the 156.djs runs successfully.
