Hi Theo, the script stopped working for me on the 14th Feb. My guess is the website changed a little bit. I'm not sure of the correct etiquette for posting a suggested work around to new issues like this. But I found a fix by making a small edit to the code around line 441. The release date value was giving this conversion error. "Conversion failed when converting date and/or time from character string."

I suspect my fix isn't the best way to do this. I'm sure you would have a much smarter way of resolving this problem, but it worked for me, so I thought I would share it. I used a SUBSTRING to strip out the 10 digit date value from the string as follows:
SUBSTRING(i.[releasedate], 17, 10) as 'releasedate'
When I used this to replace the basic select for the 'i.[releasedate]' column it seems to work. 
I've attached a copy of your full script including this edit.

I hope this helps.
Kind regards.
Tim.
