Two things to check: is your project's Datalinq Manager pointing to a localhost Datalinq Server, or a specific IP address? It could be that you're reading Datalinq values off your local server on your Designer machine. You want to be sure that wherever the project is running (BlueBox for Inception Preview, Studio for on air output) that machine can read the Datalinq server the project is pointed to.
Also, make sure the text objects using Datalinq are not published. If they are published, those values get locked into the MOS item when the graphic is added to a script.
