Top banana Daz, I've just followed what you were going to do and success! I've wrote step by step instructions of how I did it for anyone unsure up to now or struggling below.
Cheers everyone involved it was driving me nuts!

Download this folder 'Extra' ->

Open Filezilla (or similar FTP) Connect to your box
Navigate to lib->modules->4.01 delete the folder called 'Extra'
Upload the downloaded folder, restart the box and have a look on your signal finder to check it has worked.
Let us know how you've got on after!
Thanks to Gmanpanthro for simplifying the instructions!
Also let me know if the link has worked as its my first time uploading to dropbox!
I'm no expert with all this so if there is a better method or something I've missed, give us a shout!
