Still no reply from the creators as to why this never loads and very rarely works at all

Hi

I started using this extension with no problems but now it doesnt load, I can disable and enable it 20 times and refresh pages but nothing, I did email them to ask why but got no reply. This plug in is a waste of time and when it does work it still shows the already blocked channels again and again, I have the same channel blocked 5 times and it still lets it through (when the plug in works which is rarely)
Please Fix This - it clearly doesn't work properly
