wp-cache error: advanced-cache.php link does not exist

Hi all:

Just moved my site http://christian-dating-service-plus.com/ to a different server and upgraded to 2.1.3.
Problem is I can get WP-Cache(latest version) to work. Instead I get this from options after upload:

advanced-cache.php link does not exist
Create it by executing:
ln -s /home/christn1/public_html/wp-content/plugins/wp-cache/wp-cache-phase1.php /home/christn1/public_html/wp-content/advanced-cache.php
in your server

Cannot continue… fix previous problems and retry.

Tryting to “fix” almost ruined it becasue I am not technical. I read about this online, but nothing makes sense..I tried doing some of thing suggested but nearly brought my site down…..Anybody have step by step advice for dummies like me?

Thanks,

David
