Wad,
There have been a few posts to this forum about issues similar to this with Microsoft Excel. The solution has been to reinstall the Application Builder.
I would also make sure that you have the same version of Microsoft Word on the client machine as on the development machine.
The last thing is to make sure you have the latest version of the toolkit (1.0.1). You can get this from the Upgrade Advisor at http://www.ni.com/upgrade.
