Hi,
I suggest you mail to author of this program at
chuzhoi@yahoo.com
I do this frequently if I need any new functionalities.
By the way, it is also possible you are not using correct dll file. You need to download version with your corresponding db2 version. Type: db2level command to db2cmd window go get db2 version and then download correct version of dll file.
Hope this helps,
