[Plugin: NextGEN Gallery] Thumbnail layout in Blog errors

When using the nextgen gallery to upload photos onto my blog and page posts… when I am setting everything up I can line up the thumbnails in a row (example is a mutli-thumbnail post on my blog, NoHopeDesigner.com) Since updating to wordpress 2.7 when I publish my post all the thumbnails line up vertically regardless of how I set it up… Please help?
