Sorry guys, I am running little behind. You need to download the plugin from the "Additional Software Downloads" in the MLServer Help Section. It is in the BETA portion of the selection box. The other dll should be in your PM box by the time you read this. You need to copy the new dll into the c:\program files\MLServer\plugins directory.
Once you get this done, start MLserver and set up a Global Cache/Tibbo device in the plugin. Use port 1001 in the module section. Once you do this, go ahead and program a couple of commands and see if you get a response. I will send you my IM address with the dll incase you have any questions.
