Hi Craig, you could try to restart RDi with a -clean. Create a shortcut to the RDi.exe, then select properties, and on the target field, go to the end, add a space and -clean. Then save and restart.
Typically after an un-install it would prompt you for a restart. The -clean will try to clean up unused OSGI info.
If that does NOT work, you can export your settings, them create a new workspace and import your settings. (I generally export Rational Developer for i -> Configuration files before I install new plugins. Just in case I need to create a new workspace.)
