Can't get new detection rules, keep getting bad checksum

[A Beginner]

Greetings, This is my first experience in a forum, so I hope I'm doing it right...

I've been unable to download new detection rules with regularity for some months. I read the help file, but can't find the referenced drop-down menu to change mirrors. Help! (Thank you for all the work you do... I've been using Spybot for a couple of years!)

Here's a page with a screenshot of the drop-down menu(number 4):

I'll put on a link with instructions for bad checksums,in case you need it:
