Never mind, I've solved the issue.
Here is my solution:
If you are still unable to setup the Media Center tab, uninstall TV Rename, but also remove the following folder.
Then re-install the TV Rename 2.2.4 which you've downloaded from this forum/Mede8er site.
After installation, you should be able to setup the Media Center tab, at least I did! :-D
Happy TV Rename using and a happy new year to you all.
