Firefox showed nothing for me, but IE worked fine. I found the URLs to have the wrong slash in them, which is fixed now.
That flat corn stuff sure makes for a long day, doesn't it. We found that if you lower the snoots down all the way it does seem to work better, and keeps the row units up away from the dirt a bit more. We dropped the pins to the lowest hole, then lowered the bolts as far as they would go too. Set your end snoots, then one-by-one set the center ones. Make sure the tips are all level, maybe the outside ones a bit higher than the rest. This is what worked for us, so maybe it will work for you too.
