The BoonEx Trac page with upgrade instruction contains a link to the old 6.1.4 to 6.1.5 upgrade, instead of the new one. So be careful to download the patch from http://www.boonex.com/products/dolphin/download/.
Try clicking this link in this blog post: "Upgrade instructions are available on BoonEx Trac." That takes you to the page http://www.boonex.com/trac/dolphin/wiki/6.1.5to6.1.6. Then click on the link "Dolphin 6.1 Patch 6" on that page. It leads to the wrong version of the upgrade (6.1.5.zip instead of 6.1.6.zip).
Please explain your statement as it sounds vague and unclear, but it's just probably put into the wrong words.
