Hi,
You will want to check your IIS log to see if the Url is correct. You can also see if this link helps:
http://www.essentialobjects.com/doc/4/web/troubleshoot.aspxIf you still have any questions, please let us know your latest order number so that we can check if you are still qualified for free tech support. We offer free tech support for one year, which has already expired for version 3 since that version was released in 2012. However if you have a newer order you may still be able to receive support for free.
Thanks!
