InDesign CS5 won’t launch on Windows 7. I get the following error messages: 
Cannot load the LINKS.RPLN plug-in
Cannot load the FONT USAGE DIALOG.RPLN plug-in
Cannot load the XMEDIA UI.RPLN plug-in
After these error messages InDesign crashes.
Do I need to reinstall the plug-ins?
If yes, how do I do that?
