I forgot to add that after making all the changes above, you should refresh your repository, via the Refresh button in the Repository Explorer view's toolbar. Alternatively you can restart your studio (or close and open your project). Note that regardless of the method you're using you will not be able to undo these changes.
I also recommend you clear your browser cache.
If after refreshing, you're still having problems, double check that all changes are correctly spelled (spelling is crucial).
For best results, use the Firefox browser..
