I had the same problem with a lack of updating even though the script was d/l the web page. In my case the cause was the script writing the text file and saving it in what appeared to be a random position eg Win\sys, root, samurize\scripts etc so if a search of your HD reveals multiple copies at different locations then change the line that rights the file to:
(path may vary depending on where you pointed the text meters)
Code:
Set f=fs.CreateTextFile("c:\Program files\Samurize\UKTV.txt",true)
