Actually that flicker you mention is perfectly normal. All mine do that when it is installed correctly. Also good job on installing it
That previous post was a spammer, they go around to vbulletin forums and post that crap in hopes of getting ranked by google or other search engines for the garbage they are trying to push. I deleted the post, banned his ip and account, and will be installing some better security measures to ensure these deadbeats do not post here again. Hopefully i can get a special bot installed that will search for these types of posts and destroy them immediately. Either way i have it set so google and yahoo do not follow external links away from this site, so even had i left the post the spammer would not have gained anything anyhow.
