Thanks!

Forgot to mention that at present the updater isn't currently currency-aware... If there is interest I will update that

This means that if your currency symbol is anything but £ you need to open the jscript_updater.php file and set the UPDATER_CURRENCY_SYMBOL constant to your currency symbol (e.g. $)

You can also alter the displayed text by changing the UPDATER_PREFIX_TEXT constant
