Scritter Script setup

[login to view URL] click demo to see how the site works. I have this script purchased and installed in my server. please note that i have 1and1 hosting. they tend to do things a little differently. when a user name is clicked, it should go to that profile. currently mine does not, it shows a error 404 message. from scritter support, they siad i have a problem with my mod rewrite my mod_reqwrite does not work and not sure how to activate. i have learned from google that it can be done in the htaccess file but not sure how to do the code. on 1and1, i can not access server settings directly. this is what i need from you: fix my mod_rewrite via htaccess so my [login to view URL] works and goes to that specific profile. 2nd there are some parts on the admin login page: [login to view URL] i need to be able to remove all of the words :scritter i have purchased the copyright removal rights. to those that know what they are doing, this is a fast gig. thank you
