You can just go to his profile (http://leaguecheats.com/members/jimster480.2/) and post on his wall saying you purchased and you need help getting it set up, or you may PM him directly by finding his username (Jimster480) anywhere on the forums, clicking on it and clicking start a conversation.Did you mean post a comment? I could find how to pm on this site. I also dont know what to send him.
