These are standard ID components. Without knowing anything about your exact ID version, your documents or your system nobody can tell you more than that. The typical case for the missing plug-ins warnings would be that the files have been created in a newer version of ID than the one you use...
I use the latest version (Creative Cloud) and am opening docs made in CS5.
Right suspected something like this. Is there a workaround or will I have
to get plugins for movemen?
Asking other users in InDesign may work better
