Sametime broken

I had been experimenting with a way to stop the embedded sametime client working.

I found that if I moved the com.ibm.collaboration.realtime. etc files from Lotus\Notes\framework\shared\eclipse\plugins that it does indeed completely remove sametime from the toolbar/preferences/sidebar. However when I replace these files sametime does not re-appear. Is there some othe setting or config file I need to change to get it back?

A re-install of the client will get it back but I was hoping there wold be a quicker way.

Thanks
