Keith's powershell script for Dell Driver Pack Catalog

Hello, i've been using the script on this page:

keithga.wordpress.com/2014/08/21/dell-driver-pack-catalog/

for a while now, but it seems like dell either changed some variables in it or did something else as it's not working anymore. I do realize that perhaps my best bet would be to contact the author directly to see if there are any fixes for it, but it seems that he's no longer keen on working with anything involving dell or any other competing brand as i think he's now working for some other big OEM :)

Anyway, if any of you know why it's stopped working as of May i'de be delighted to know, thanks :)
