The document uses one or more plug-ins which are not currently available on your system.
and several others .rpln files
CANNOT open the file . Please upgrade your plugins to their laatest versions or upgrade to the latest version of Adobe Indesign. I have CS5
CS6 is the latest version for Adobe products. CS5 is two versions old at this time.
What Ned said. These warnings appear if you try to open newer version docs in older versions.
